wifi: mt76: mt7996: wake MCU waiters before aborting scan in L1 SER

Browse Source 
The L1 reset path calls mt76_abort_scan() between setting MT76_MCU_RESET
and waking mcu.wait. A scan work blocked on an in-flight MCU command
does not re-evaluate its wait condition until woken, so the
cancel_delayed_work_sync() inside the abort sleeps out the full MCU
timeout before recovery can proceed, adding several seconds of SER
latency. mt7996_mac_full_reset() and the mt7915 counterpart already
order the wake-up first.

Wake mcu.wait immediately after setting MT76_MCU_RESET so in-flight
commands bail out before the abort synchronises against them.
