vhost-user: unregister slave req handler at cleanup time
If the backend sends a request just before closing the socket,
the aio dispatcher might schedule its reading after the vhost
device has been cleaned, leading to a NULL pointer dereference
in slave_read();
vhost_user_cleanup() already closes the socket but it is not
enough, the handler has to be unregistered.
