quota: Allow each filesystem to specify which quota types it supports
Currently all filesystems supporting VFS quota support user and group quotas. With introduction of project quotas this is going to change so make sure filesystem isn't called for quota type it doesn't support by introduction of a bitmask determining which quota types each filesystem supports.
