virtio-blk and virtio-serial need to free VirtQueueElements during device reset. Simply calling g_free(elem) is not enough because the scatter-gather list should be unmapped and vq->inuse must be decremented.
These patches address the issue. I am not including a patch that changes vq->inuse = 0 to assert(!vq->inuse) in virtio_reset() yet because virtio-9p, virtio-gpu, and virtio-net have code paths that do not decrement vq->inuse.
