features/quota: maintain correct link_count in ancestry building
codepath. Ancestry building codepath can be executed simultaneously when a file has hardlinks. So, following fixes are needed: * modify local->link_count under locks in ancestry building codepath. * before invoking check_limit on newly constructed parents, link_count should not be set, but instead incremented by as many number of new invocations of check_limit. * decrementing link_count and the check whether the count has hit zero to resume the waiting call_stub should be atomic.
