Chuck Lever 3a66ad7ea7 SUNRPC: Use RMW bitops in single-threaded hot paths
[ Upstream commit 28df0988815f63e2af5e6718193c9f68681ad7ff ]

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.
