    net/virtio: fix check of threshold for Tx freeing
    
    Like most drivers, make the fast path of virtio_xmit_cleanup() behave as
    described by the comments of rte_eth_txconf::tx_free_thresh ([0]):
        Start freeing Tx buffers if there are
        less free descriptors than this value.
    
    The rationale behind this change is that:
      * vq->vq_nentries is set during device probe
        with the queue size specified by vhost backend,
        this value does not reflect the real nb_tx_desc
      * the real available tx desc is set to vq->vq_free_cnt
        via the nb_tx_desc param of rte_eth_tx_queue_setup() API
      * so `nb_used > vq->vq_nentries - vq->vq_free_thresh` could never be true
        if say nb_tx_desc=2048, vq->vq_nentries=4096, vq->vq_free_thresh=32,
        see bug report 1716 ([1]) for details.
