[PATCH] RPC: Report connection errors properly when mounting with "soft"
Fix up xprt_connect_status: the soft timeout logic was clobbering tk_status,
so TCP connect errors were not properly reported on soft mounts.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP.
