scftorture: Count single_rpc offline failures in statistics outputgrafted

scf_torture_stats_print() aggregates each invoker thread's counters
into a local scf_statistics structure before printing, but the
n_single_rpc_ofl field is missing from the aggregation loop.  As a
result, the "single_rpc_ofl" value printed in the statistics line is
always zero, even when smp_call_function_single() invocations for the
RPC test have failed due to offline CPUs and been counted by the
invoker threads.

Add the missing accumulation so that the printed value reflects the
actual counts.

+	help
+	  Universal Serial Bus (USB) is a specification for a serial bus
+	  subsystem which offers higher speeds and more features than the
+	  traditional PC serial port.  The bus supplies power to peripherals
+	  and allows for hot swapping.  Up to 127 USB peripherals can be
+	  connected to a single USB host in a tree structure.
+	  
+	  The USB host is the root of the tree, the peripherals are the
+	  leaves and the inner nodes are special USB devices called hubs.
+	  Most PCs now have USB host ports, used to connect peripherals
+	  such as scanners, keyboards, mice, modems, cameras, disks,
+	  flash memory, network links, and printers to the PC.
+
+	  Say Y here if your computer has a host-side USB port and you want
+	  to use USB devices.  You then need to say Y to at least one of the
+	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
+	  controller, such as "UHCI HCD support" or "OHCI HCD support",
+	  and "EHCI HCD (USB 2.0) support" except for older systems that
+	  do not have USB 2.0 support.  It doesn't normally hurt to select
+	  them all if you are not certain.
+
+	  If your system has a device-side USB port, used in the peripheral
+	  side of the USB protocol, see the "USB Gadget" framework instead.
+
+	  After choosing your HCD, then select drivers for the USB peripherals
+	  you'll be using.  You may want to check out the information provided
+	  in <file:Documentation/usb/> and especially the links given in
+	  <file:Documentation/usb/usb-help.rst>.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called usbcore.
+
+config USB_PCI
+	bool "PCI based USB host interface"
+	depends on PCI
+	default y
+	help
+	  Many embedded system SOCs (e.g. freescale T2080) have both
+	  PCI and USB modules with the USB module directly controlled by
+	  registers and having no relationship to the PCI module.
+
+	  If you have such a device you may say N here and PCI related code
+	  will not be built in the USB driver.
+
+config USB_PCI_AMD
+	bool "AMD PCI USB host support"
+	depends on USB_PCI && HAS_IOPORT
+	default X86 || MACH_LOONGSON64 || PPC_PASEMI
+	help
+	  Enable workarounds for USB implementation quirks in SB600/SB700/SB800
+	  and later south bridge implementations. These are common on x86 PCs
+	  with AMD CPUs but rarely used elsewhere, with the exception of a few
+	  powerpc and mips desktop machines.
