wifi: mt76: mt7996: limit work in set_bitrate_mask

Browse Source 
Calls to mt7996_set_bitrate_mask() would propagate work for all stations
on the ieee80211_hw regardless of the vif specified in the call. To
prevent unnecessary work in FW, limit setting the sta_rate to only the
specified vif in mt7996_sta_rate_ctrl_update().
