cpu_to_be32() is wrong since vhd_type is an enum constant
(just a regular CPU-endian integer).

Please use 'git send-email' to send patches. Neither 'git am' nor
'patch' can seem to apply this patch (firstly because this is not a
plain text, but a multipart email, but even when doing the extra effort
of saving just the text part it doesn't work).
The same is true for your other patch.
