[PATCH] RPC: kick off socket connect operations faster 

Make the socket transport kick the event queue to start socket connects
 immediately.  This should improve responsiveness of applications that are
 sensitive to slow mount operations (like automounters).

 We are now also careful to cancel the connect worker before destroying
 the xprt.  This eliminates a race where xprt_destroy can finish before
 the connect worker is even allowed to run.

 Test-plan:
 Destructive testing (unplugging the network temporarily).  Connectathon
 with UDP and TCP.  Hard-code impossibly small connect timeout.
