mt76: overwrite qid for non-bufferable mgmt frames

Browse Source 
Overwrite hw queue id for non-bufferable management frames if the hw
support always txq (altxq) in order to be in sync with mac txwi code

Fixes: cdad487405 ("mt76: mt7615: add dma and tx queue initialization for MT7622")
Fixes: f40ac0f3d3 ("mt76: mt7615: introduce mt7663e support")
