virtio: Fix used_idx wrap-around
The more_used() function compares the vq->vring.used->idx with last_used_idx.
Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an
unsigned int, this results in unpredictable behavior when vq->vring.used->idx
wraps around.
This patch corrects this by changing last_used_idx to the correct type.
