SUNRPC fix regression in umount of a secure mount

commit ec6017d9035986a36de064f48a63245930bfad6f upstream.

If call_status returns ENOTCONN, we need to re-establish the connection
state after. Otherwise the client goes into an infinite loop of call_encode,
call_transmit, call_status (ENOTCONN), call_encode.

Fixes: c8485e4d63 ("SUNRPC: Handle ECONNREFUSED correctly in xprt_transmit()")
