wifi: mt76: mt7996: set MT76_MCU_RESET before waking MCU waiters on full reset
mt7996_mac_full_reset() called wake_up(&dev->mt76.mcu.wait) without first
setting MT76_MCU_RESET. The MCU response wait condition only checks the
response queue and that bit, so the wake-up released nobody: a thread
blocked in an MCU command against the dead firmware (typically holding
dev->mt76.mutex) stayed asleep until its multi-second timeout, stalling
recovery. Set the bit before the wake-up, as mt7915 does.
