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. Signed-off-by: Joel Fernandes <joelagnelf@nvidia.com> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

+description: |
+ A generic interrupt counter to measure interrupt frequency. It was developed
+ and used for agricultural devices to measure rotation speed of wheels or
+ other tools. Since the direction of rotation is not important, only one
+ signal line is needed.
+ Interrupts or gpios are required. If both are defined, the interrupt will
+ take precedence for counting interrupts.
