[PATCH] libqos/virtio.c: Correct 'flags' reading in qvirtqueue_kick

[Zheyu Ma]

In qvirtqueue_kick(), the 'flags' were previously being incorrectly read from
vq->avail instead of the correct vq->used location. This update ensures 'flags'
are read from the correct location as per the virtio standard.
