Our shutdown binary that takes over as PID 1 when shutting down puts great efforts into a sync() that comes with a time-out once sync'ing process stops. If we'd add another dumb sync() here, we kinda defeat all it is good for. Hence, let's keep the sync() in for most codepats, but let's disable it for the final shutdown logic when we transition back into the exitrd. After all we sync()ed more than enough here, no need to sync() even more.
