[PATCH RFC 1/2] scftorture: Count single_rpc offline failures in statistics output

["Paul E. McKenney" <paulmck@kernel.org>]

From: Joel Fernandes <joelagnelf@nvidia.com>

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.
