GFS2: add barrier/nobarrier mount options
Currently gfs2 issues barrier unconditionally. There are various reasons to disable them, be that just for testing or for stupid devices flushing large battert backed caches. Add a nobarrier option that matches xfs and btrfs for this. Also add a symmetric barrier option to turn it back on at remount time.
