Transport's release() and destruct() are called when de-assigning the
vsock transport. These callbacks can touch some socket state like
sock flags, sk_state, and peer_shutdown.
Since we are reassigning the socket to a new transport during
vsock_connect(), let's reset these fields to have a clean state with
the new transport.
