SUNRPC: Add a trace point in svc_xprt_deferred_close

Browse Source 
The trace point in svc_xprt_close() reports only some local close
requests. Try to capture more local close requests.

Note that "trace-cmd record -T -e sunrpc:svc_xprt_close" will
neatly capture the identity of the caller requesting the close.
