Remove mt76_queue dependency from tx_complete_skb function pointer and
rely on mt76_tx_qid instead. Remove flush from tx_complete_skb
signature. This is a preliminary patch to introduce mt76_sw_queue
support

Introduce mt76_sw_queue data structure in order to support new
chipsets (e.g. mt7615) that have a shared hardware queue for all traffic
identifiers. mt76_sw_queue will be used to track outstanding packets
