libvhost-user: quit when no more data received
End processing of messages when VHOST_USER_NONE is received. Without this we run into a vubr_panic() call and get "PANIC: Unhandled request: 0" Signed-off-by: Jens Freimann <jfreiman@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
