Lorenzo BianconiandFelix Fietkau f76e25fe5a mt76x2: fix WMM parameter configuration 
Fix hw queue configuration since mt76x2 devices use a reverse queue
enumeration respect to mac80211 one:
 - 0: AC_BE
 - 1: AC_BK
 - 2: AC_VI
 - 3: AC_VO

The issue can be reproduced sending two concurrent flow using
two separate queues:
 - VO: 20Mbps UDP traffic
 - BE: TCP traffic

In this scenario the UDP traffic will be blocked by the TCP one.
Fix it configuring properly WMM hw queue parameters
