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

[swhiteho@redhat.com]

From: Bob Peterson <rpeterso@redhat.com>

This patch is for bugzilla bug #245663.  This crosswrites a fix from
gfs1 (bz #210369) so that the mount options are reset properly upon
remount.  This was tested on system trin-10.
