virtio-rng: use virtqueue_get_avail_bytes, fix migration

Popping an elem from the vq just to find out its length causes problems
with save/load later on.  Use the new virtqueue_get_avail_bytes()
function instead, saves us the complexity in the migration code, as well
as makes the migration endian-safe.
