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.
