sparse reports an error on some data that gets converted from be32.

That's because that data is typed u32 instead of __be32.

Fix it.

the reason for this sparse error is that the data variables is
then parsed with a be32_to_cpup() and I think that's not
necessary.

I think the real fix here is to not use be32_to_cpup().
