This patch fixes:
1. I checked 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);
3. change some format of quota log, based upon
https://bugzilla.lustre.org/show_bug.cgi?id=18574#c65
