Lorenzo BianconiandFelix Fietkau 1e91eadc9d wifi: mt76: wed: use proper wed reference in mt76 wed driver callabacks 
MT7996 driver can use both wed and wed_hif2 devices to offload traffic
from/to the wireless NIC. In the current codebase we assume to always
use the primary wed device in wed callbacks resulting in the following
crash if the hw runs wed_hif2 (e.g. 6GHz link).
