__mt76_tx_queue_skb() overrides the wcid passed by the driver with
sta->drv_priv, so the wcid might incorrectly be changed after TX,
causing wcid->non_aql_packets to be counted on the wrong wcid. For
example, on the AP side, if a station's setup link is the 5G link and
the station uses 2G to transmit a frame, the value of non_aql_packets
is increased on the 5G wcid but decreased on the 2G wcid. Once the
inflated counter exceeds MT_MAX_NON_AQL_PKT, the TX scheduler
permanently refuses to service the station.
Drop the reassignment and account on the wcid used for transmission.
This also records the actual wcid in the queue entry.
