net: airoha: fix BQL imbalance in TX path

In the Linux kernel, the following vulnerability has been resolved:

net: airoha: fix BQL imbalance in TX path

Fix a possible BQL imbalance in airoha_dev_xmit(), where inflight
packets are accounted only for the AIROHA_NUM_TX_RING netdev TX
queues. The queue index is computed as:

    qid = skb_get_queue_mapping(skb) % ARRAY_SIZE(qdma->q_tx)
    txq = netdev_get_tx_queue(dev, qid);

However, airoha_qdma_tx_napi_poll() accounts completions across all
netdev TX queues (num_tx_queues), leading to inconsistent BQL
accounting.

Also reset all netdev TX queues in the ndo_stop callback.
