VSOCK: set POLLOUT | POLLWRNORM for TCP_CLOSING
select(2) with wfds but no rfds must return when the socket is shut down by the peer. This way userspace notices socket activity and gets -EPIPE from the next write(2). Currently select(2) does not return for virtio-vsock when a SEND+RCV shutdown packet is received. This is because vsock_poll() only sets POLLOUT | POLLWRNORM for TCP_CLOSE, not the TCP_CLOSING state that the socket is in when the shutdown is received.
