This belongs in scratch_mkfs_sized(), as gfs2 specific code. You
have the size of the fs to be made there, so set the limit
appropriately there.

As it is, it's worth considering that this is exposing a mkfs.gfs2
bug in that it doesn't handle small filesystem sizes correctly by
default....

Cheers,

Dave.
