Description: fix lqs' reference which won't be put in some situations
Details : This patch fixes:
- 1. In quota_check_common(), this function will check quota
- for user and group, but only send one return via "pending".
- In most cases, the pendings should be same. But that is not
- always the case.
- 2. If quotaoff runs between lquota_chkquota() and
- lquota_pending_commit(), the same thing will happen too.
- That is why it comes:
- - if (!ll_sb_any_quota_active(qctxt->lqc_sb))
- - RETURN(0);
