wifi: mt76: account non-AQL frames per peer rather than per link
The driver increments wcid->non_aql_packets when a frame goes to the
hardware queue. The completion path decrements the counter again.
For an MLO peer, the hardware reports the completion on the link that it
used for the transmission. This link can differ from the link that the
driver queued the frame on. In that case, the increment and the
decrement go to different link wcids, and the count drifts upwards until
it blocks the station.
Keep the count on the wcid of the primary link, like the other peer-wide
state.
