virtio: fix wrong queue index

We should provide VIRTIO_PCI_QUEUE_SEL with vq->vq_queue_idx,
but not vq->queue_id.

vq->queue_id is the queue id from rte_eth_rx/tx_queue_setup(),
which always starts from 0 no matter which queue it is. However,
for virtio, even number is for RX queue, and odd number is for
TX queue.
