quota: Split ->set_xstate callback into two
Split ->set_xstate callback into two callbacks - one for turning quotas on (->quota_enable) and one for turning quotas off (->quota_disable). That way we don't have to pass quotactl command into the callback which seems cleaner. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
