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:
+ Directly access the registers of backend Y. Typical usage is:
+
+ Reading address 0x50
+ echo 0x50 > direct_reg_access
+ cat direct_reg_access
+
+ Writing address 0x50
+ echo 0x50 0x3 > direct_reg_access
+ //readback address 0x50
+ cat direct_reg_access
