xs_tcp_finish_connecting() can return -ENOTCONN but the switch statement in xs_tcp_setup_socket() treats that as an unhandled error. If we treat it as a known error it would propagate back to call_connect_status() which does handle that error code. This appears to be the intention of the commit (given below) which added -ENOTCONN as a return status for xs_tcp_finish_connecting(). So add -ENOTCONN to the switch statement as an error to pass through to the caller.
