wifi: mt76: mt7921: fix the lock inversion in suspend and resume

Browse Source 
Same inversion as the config path, same one word fix, missed the
first time. Both are called with the wiphy mutex held, so the walk
can rely on that instead of taking the list mutex.

No new splat: same class pair as the accepted fix, and lockdep
reports a pair once per boot.
