bhyve smbios type 3 structure is incorrect
If you look at the SMBIOS specification, we'll find something is
missing. In particular at offset 0Dh is supposed to be the OEM-defined
field. This should go between security and height. It is not legal to
actually skip this and will lead to other folks not properly
interpreting later parts of the table.
