SUNRPC: Remove low signal-to-noise tracepoints
I'm about to add more information to the server-side SUNRPC tracepoints, so I'm going to offset the increased trace log consumption by getting rid of some tracepoints that fire frequently but don't offer much value. trace_svc_xprt_received() was useful for debugging, perhaps, but is not generally informative. trace_svc_handle_xprt() reports largely the same information as trace_svc_xdr_recvfrom(). As a clean-up, rename trace_svc_xprt_do_enqueue() to match svc_xprt_dequeue(). Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
