Subject: [PATCH] [GFS2] Revert remounting w/o acl option leaves acls enabled

From: Steven Whitehouse <swhiteho@...hat.com>

This reverts commit 569a7b6c2e8965ff4908003b925757703a3d649c. The
code was correct originally. The default setting for ACLs after a
remount should be to be the same as before the remount.
