vhost: Always store new kick fd on vhost_svq_set_svq_kick_fd
We can unbind twice a file descriptor if we call twice
vhost_svq_set_svq_kick_fd because of this. Since it comes from vhost and
not from SVQ, that file descriptor could be a different thing that
guest's vhost notifier.
Likewise, it can happens the same if a guest start and stop the device
multiple times.
