SUNRPC: Fix a NULL pointer deref in trace_svc_stats_latency()

[ Upstream commit 5c11720767f70d34357d00a15ba5a0ad052c40fe ]

Some paths through svc_process() leave rqst->rq_procinfo set to
NULL, which triggers a crash if tracing happens to be enabled.

Fixes: 89ff87494c6e ("SUNRPC: Display RPC procedure names instead of proc numbers")
