Chuck Lever 28df098881 SUNRPC: Use RMW bitops in single-threaded hot paths
I noticed CPU pipeline stalls while using perf.

Once an svc thread is scheduled and executing an RPC, no other
processes will touch svc_rqst::rq_flags. Thus bus-locked atomics are
not needed outside the svc thread scheduler.
