When the network layer reports a connection close, the RPC task
 waiting to reconnect should be notified so it can retry immediately
 instead of waiting for the normal connection establishment timeout.

 for RPC over TCP socket idle timeouts.

 Test-plan:
 Destructive testing with NFS over TCP mounts.
