selftests/ftrace: Fix unique symbol check in kprobe_non_uniq_symbol.tcgrafted

The current regex also matches symbols in modules, which makes the
test fail on s390 where name_show is present only once in the kernel,
but also multiple times in modules:

000001b1401cdc20 t name_show
000001b0c05e6c40 t name_show    [mdev]
000001b0c0495f30 t name_show    [i2c_core]

Fix this by changing the regular expression to only match the function
name.

+Description:	(RW) Reports the current state of the QAT device. Write to
+		the file to start or stop the device.
+
+		The values are:
+
+		* up: the device is up and running
+		* down: the device is down
+
+
+		It is possible to transition the device from up to down only
+		if the device is up and vice versa.
+
+		This attribute is available for qat_4xxx and qat_6xxx devices.

+Description:	(RW) Reports the current configuration of the QAT device.
+		Write to the file to change the configured services.
+
+		One or more services can be enabled per device.
+		Certain configurations are restricted to specific device types;
+		where applicable this is explicitly indicated, for example
+		(qat_6xxx) denotes applicability exclusively to that device series.
+
+		The available services include:
+
+		* sym: Configures the device for symmetric cryptographic operations.
+		* asym: Configures the device for asymmetric cryptographic operations.
+		* dc: Configures the device for compression and decompression
+		  operations.
+		* dcc: Similar to dc, but with the additional dc chaining feature
+		  enabled, cipher then compress (qat_6xxx), hash then compression.
+		  If this is not required choose dc.
+		* decomp: Configures the device for decompression operations (qat_6xxx).
+
+		Service combinations are permitted for all services except dcc.
+		On QAT GEN4 devices (qat_4xxx driver) a maximum of two services can be
+		combined and on QAT GEN6 devices (qat_6xxx driver ) a maximum of three
+		services can be combined.
+		The order of services is not significant. For instance, sym;asym is
+		functionally equivalent to asym;sym.
+
+		It is possible to set the configuration only if the device
+		is in the `down` state (see /sys/bus/pci/devices/<BDF>/qat/state)
+
+		The following example shows how to change the configuration of
+		a device configured for running crypto services in order to
+		run data compression::
+
+			# cat /sys/bus/pci/devices/<BDF>/qat/state
+			up
+			# cat /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			sym;asym
+			# echo down > /sys/bus/pci/devices/<BDF>/qat/state
+			# echo dc > /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			# echo up > /sys/bus/pci/devices/<BDF>/qat/state
+			# cat /sys/bus/pci/devices/<BDF>/qat/cfg_services
+			dc
+
+		This attribute is available for qat_4xxx and qat_6xxx devices.

+Description:	(RW) This configuration option provides a way to force the device into remaining in
+		the MAX power state.
+		If idle support is enabled the device will transition to the `MIN` power state when
+		idle, otherwise will stay in the MAX power state.
+		Write to the file to enable or disable idle support.
+
+		The values are:
+
+		* 0: idle support is disabled
+		* 1: idle support is enabled
+
+		Default value is 1.
+
+		It is possible to set the pm_idle_enabled value only if the device
+		is in the `down` state (see /sys/bus/pci/devices/<BDF>/qat/state)
+
+		The following example shows how to change the pm_idle_enabled of
+		a device::
+
+			# cat /sys/bus/pci/devices/<BDF>/qat/state
+			up
+			# cat /sys/bus/pci/devices/<BDF>/qat/pm_idle_enabled
+			1
+			# echo down > /sys/bus/pci/devices/<BDF>/qat/state
+			# echo 0 > /sys/bus/pci/devices/<BDF>/qat/pm_idle_enabled
+			# echo up > /sys/bus/pci/devices/<BDF>/qat/state
+			# cat /sys/bus/pci/devices/<BDF>/qat/pm_idle_enabled
+			0

+		This attribute is available for qat_4xxx and qat_6xxx devices.

+Contact:	qat-linux@intel.com
+Description:
+		(RW) This attribute provides a way for a user to query a
+		specific ring pair for the type of service that it is currently
+		configured for.
+
+		When written to, the value is cached and used to perform the
+		read operation. Allowed values are in the range 0 to N-1, where
+		N is the max number of ring pairs supported by a device. This
+		can be queried using the attribute qat/num_rps.
+
+		A read returns the service associated to the ring pair queried.
+
+		The values are:
+
+		* dc: the ring pair is configured for running compression services
+		* sym: the ring pair is configured for running symmetric crypto
+		  services
+		* asym: the ring pair is configured for running asymmetric crypto
+		  services
+
+		Example usage::
+
+			# echo 1 > /sys/bus/pci/devices/<BDF>/qat/rp2srv
+			# cat /sys/bus/pci/devices/<BDF>/qat/rp2srv
+			sym

+		Write to the attribute to enable or disable device auto reset.
+
+		Device auto reset is disabled by default.
+
+		The values are:
+
+		* 1/Yy/on: auto reset enabled. If the device encounters an
+		  unrecoverable error, it will be reset automatically.
+		* 0/Nn/off: auto reset disabled. If the device encounters an
+		  unrecoverable error, it will not be reset.
