Felix Fietkau a03ef0aab9 wifi: mt76: mt7921: fix deadlock in mt7921_abort_roc ...

When mt7921_abort_roc is called with dev->mutex held, it can deadlock while
calling cancel_work_sync(&phy->roc_work), because the work function could
be waiting to acquire the mutex.

Fix this by flushing the work before taking the mutex
