quota: turn quotas off when remounting read-only



Turn off quotas before filesystem is remounted read only.  Otherwise quota
will try to write to read-only filesystem which does no good...  We could
also just refuse to remount ro when quota is enabled but turning quota off
is consistent with what we do on umount.
