We can be less restrictive about pure data children than those with
metadata on them.

For bdrv_format_default_perms(), we keep the safe option of
bdrv_default_perms_for_metadata() (until we drop
bdrv_format_default_perms() altogether).

That means that bdrv_default_perms_for_data() is unused at this point.
We will use it for all children that have the DATA role, but not the
METADATA role.  So far, no child has any role, so we do not use it, but
that will change.
