    DARWIN: Drop afs_event lock before destroying it
    
    On macOS arm64, a lock (lck_mtx_t) must be released (lck_mtx_unlock)
    before it can be destroyed/freed (lck_mtx_free -> lck_mtx_destroy). If
    this rules isn't respected, the operating system in question will panic
    with the following message:
    
      panic("lck_mtx_assert(): mutex (%p) not owned", lock);
    
    Unfortunately, the current shutdown process of the osi_sleep module
    doesn't respect this rule. As a result, macOS arm64 panics when the
    OpenAFS client is shut down/restarted. To fix this problem, release
    afs_event->lck (EVTLOCK_UNLOCK) before destroying it (EVTLOCK_DESTROY).
