GFS2: drop rindex glock to refresh rindex list
When a gfs2 filesystem is grown, it needs to rebuild the rindex list to be able to use the new space. gfs2 does this when the rindex is marked not uptodate, which happens when the rindex glock is dropped. However, on a single node setup, there is never any reason to drop the rindex glock, so gfs2 never invalidates the the rindex. This patch makes gfs2 automatically drop the rindex glock after filesystem grows, so it can refresh the rindex list.
