Jorge E. Moreira 8c00b8829f vhost-user-backend: Avoid losing vring kicks
By registering the file descriptors only when the queue is ready and
enabled. This fixes a race in which a buffer could be added to the queue
and the kick sent after registration but before it being enabled which
causes the kick to be lost and the event never delivered to the backend.
This was particularly prevalent when restoring a snapshot.
