wifi: mt76: mt7996: disable rx header translation for BMC entry

When a BMC wtbl of station interface is correctly set with peer address,
HW will do rx header translation for broadcast data packets, which makes
mac80211 unable to find the corresponding ieee80211_sta and drop the
packets. To fix this, disable HW rx header translation for BMC entry.
