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.

+	tristate "SLIP (serial line) support"
+	depends on TTY
+	help
+	  Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
+	  connect to your Internet service provider or to connect to some
+	  other local Unix box or if you want to configure your Linux box as a
+	  Slip/CSlip server for other people to dial in. SLIP (Serial Line
+	  Internet Protocol) is a protocol used to send Internet traffic over
+	  serial connections such as telephone lines or null modem cables;
+	  nowadays, the protocol PPP is more commonly used for this same
+	  purpose.
+
+	  Normally, your access provider has to support SLIP in order for you
+	  to be able to use it, but there is now a SLIP emulator called SLiRP
+	  around (available from
+	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+	  allows you to use SLIP over a regular dial up shell connection. If
+	  you plan to use SLiRP, make sure to say Y to CSLIP, below. The
+	  NET-3-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, explains how to
+	  configure SLIP. Note that you don't need this option if you just
+	  want to run term (term is a program which gives you almost full
+	  Internet connectivity if you have a regular dial up shell account on
+	  some Internet connected Unix computer. Read
+	  <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
+	  support will enlarge your kernel by about 4 KB. If unsure, say N.
+
+	  To compile this driver as a module, choose M here. The module
+	  will be called slip.

+config SLIP_COMPRESSED
+	bool "CSLIP compressed headers"
+	depends on SLIP
+	select SLHC
+	help
+	  This protocol is faster than SLIP because it uses compression on the
+	  TCP/IP headers (not on the data itself), but it has to be supported
+	  on both ends. Ask your access provider if you are not sure and
+	  answer Y, just in case. You will still be able to use plain SLIP. If
+	  you plan to use SLiRP, the SLIP emulator (available from
+	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+	  allows you to use SLIP over a regular dial up shell connection, you
+	  definitely want to say Y here. The NET-3-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, explains how to configure
+	  CSLIP. This won't enlarge your kernel.
+
+config SLIP_SMART
+	bool "Keepalive and linefill"
+	depends on SLIP
+	help
+	  Adds additional capabilities to the SLIP driver to support the
+	  RELCOM line fill and keepalive monitoring. Ideal on poor quality
+	  analogue lines.
+
+config SLIP_MODE_SLIP6
+	bool "Six bit SLIP encapsulation"
+	depends on SLIP
+	help
+	  Just occasionally you may need to run IP over hostile serial
+	  networks that don't pass all control characters or are only seven
+	  bit. Saying Y here adds an extra mode you can use with SLIP:
+	  "slip6". In this mode, SLIP will only send normal ASCII symbols over
+	  the serial device. Naturally, this has to be supported at the other
+	  end of the link as well. It's good enough, for example, to run IP
+	  over the async ports of a Camtec JNT Pad. If unsure, say N.
