SUNRPC: Add a trace point in svc_xprt_deferred_close

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. Signed-off-by: Chuck Lever <[email protected]>
