[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.
