SUNRPC: Fix backchannel latency metrics
commit 8729aaba74626c4ebce3abf1b9e96bb62d2958ca upstream.
I noticed that for callback requests, the reported backlog latency
is always zero, and the rtt value is crazy big. The problem was that
rqst->rq_xtime is never set for backchannel requests.
Fixes: 78215759e20d ("SUNRPC: Make RTT measurement more ... ")
