wifi: mt76: mt7925: stop init retries on hung bus

Browse Source 
Stop retrying hardware init once the bus is marked hung.

The control path is no longer usable at that point, so more retries only
issue failing device accesses, including MCU commands or register
operations, and delay teardown. Exit early and let the failed device be
torn down quickly.
