As with regular block groups, it would probably be better to limit the
bitmaps and inode tables to anywhere inside the flexbg instead of the
start.  That would allow, for example, INCOMPAT_FLEXBG to be enabled
on an existing filesystem and the metadata could be moved together as
space becomes available.
