I assume that you mean you switched mount -o uquota,gquota for
mount -o uquota,pquota or something like that?

If any quota is on at mount time, and the "checked" flag is not present
in the on-disk superblock, then quotacheck gets run.
In general, we do accounting even if we don't do enforcement; i.e.
having no quotas defined does not man that quota activity isn't
happening - it is, because accounting happens regardless.

This was likely fixed upstream in 3.16

xfs: fix Q_XQUOTARM ioctl
and should be fixed in sufficiently up to date centos7 as well.
but removing quota inodes won't obviate the need for a quotacheck,
I'm afraid.
