Subject: [PATCH 25/26] staging/lustre/autoconf: remove quota_on/quota_off checks

From: James Simmons <uja.ornl@...il.com>

With the rewrite of the Lustre quota code we no longer
need ll_quota_[on/off]. Those obsolete methods touched
linux kernel internals that have changed over time.
With ll_quota_[on/off[ gone we can remove all the
quota autoconf that was required.
