Osama Muhammad 5c28478af3 gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump 
[ Upstream commit 8877243beafa7c6bfc42022cbfdf9e39b25bd4fa ]

Syzkaller has reported a NULL pointer dereference when accessing
rgd->rd_rgl in gfs2_rgrp_dump().  This can happen when creating
rgd->rd_gl fails in read_rindex_entry().  Add a NULL pointer check in
gfs2_rgrp_dump() to prevent that.
