SUNRPC: Don't leak sockets in xs_local_connect()

SUNRPC: Don't leak sockets in xs_local_connect()

commit aad41a7d7cf6c6fa804c872a2480f8e541da37cf upstream.

If there is still a closed socket associated with the transport, then we
need to trigger an autoclose before we can set up a new connection.
