[GFS2] Reduce inode size by merging fields
There were three fields being used to keep track of the location of the most recently allocated block for each inode. These have been merged into a single field in order to better keep the data and metadata for an inode close on disk, and also to reduce the space required for storage. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
