Chuck Lever 8cc0e63ba8 Revert "SUNRPC: Use RMW bitops in single-threaded hot paths" 
commit 7827c81f02 upstream.

The premise that "Once an svc thread is scheduled and executing an
RPC, no other processes will touch svc_rqst::rq_flags" is false.
svc_xprt_enqueue() examines the RQ_BUSY flag in scheduled nfsd
threads when determining which thread to wake up next.

Found via KCSAN.
