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.

+	  Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
+	  the lower) part of the X.25 protocol. It offers a reliable
+	  connection service to exchange data frames with one other host, and
+	  it is used to transport higher level protocols (mostly X.25 Packet
+	  Layer, the higher part of X.25, but others are possible as well).
+	  Usually, LAPB is used with specialized X.21 network cards, but Linux
+	  currently supports LAPB only over Ethernet connections. If you want
+	  to use LAPB connections over Ethernet, say Y here and to "LAPB over
+	  Ethernet driver" below. Read
+	  <file:Documentation/networking/lapb-module.rst> for technical
+	  details.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called lapb.  If unsure, say N.
