Since it is stupid to store flags which have no effect, just store 0 unconditionally and don't bother loading it from disk. Note that userspace could have stored some flags there via Q_SETINFO quotactl and then later read them (although flags have no effect) but I'm pretty sure noone does that (most definitely quota-tools don't and quota interface doesn't have too much other users).
