GFS2: make sure rgrps are up to date in func gfs2_blk2rgrpd
This patch adds a call to gfs2_rindex_update from function gfs2_blk2rgrpd and removes calls to it that are made redundant by it. The problem is that a gfs2_grow can add rgrps to the rindex, then put those rgrps into use, thus rendering the rindex we read in at mount time incomplete.
