Because nbd_client_close removes the I/O handlers for the client socket, there is no way that any suspended coroutines are restarted. This will be a problem with the QEMU embedded NBD server, because we will have a QMP command to forcibly close all connections with the clients. Instead, we can exploit the reference counting of NBDClients; shutdown the client socket, which will make it readable and writeable. Also call the close callback, which will release the user's reference. The coroutines then will fail and exit cleanly, and release all remaining references, until the last refcount finally triggers the closure of the client.
