[GFS2] Merge the rd_last_alloc_meta and rd_last_alloc_data fields
We don't need to keep track of when we last allocated data and metadata separately since the only thing thats important when searching for a free block is whether its free or not, which is independent from what type of block it is. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
