mt76: mt7615: fix hw queue mapping

Browse Source 
mt7622/mt7663 chipsets rely on a fixed reverse queue map order respect
to mac80211 one:
- q(0): IEEE80211_AC_BK
- q(1): IEEE80211_AC_BE
- q(2): IEEE80211_AC_VI
- q(3): IEEE80211_AC_VO

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