[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.
