[5/7] smbios: Clean up smbios_add_field() parameters

Having size preceed the associated pointer is odd.  Swap them, and fix
up the types.

Can you proceed to fix the spelling of "precede"? :)

Still wrong I think.

I trust gcc would have caught any missed calls ("creates pointer from
integer without cast" or some such). So the only problem (I think) is in
qemu_uuid_parse() which should be semi-auto-fixed when you rebase.

Sure.
