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.

 This reverts a change made in 2.6.6 as part of adding client support
 for RPC over TCP socket idle timeouts.

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