Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/mediatek/mt76/mt7915/mcu.c: In function 'mt7915_mcu_sta_txbf_type':
drivers/net/wireless/mediatek/mt76/mt7915/mcu.c:1805:21: warning:
 variable 'msta' set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
