[PATCH 1/2] hw/smbios: Fix OEM strings table option validation

[Akihiko Odaki]

qemu_smbios_type11_opts did not the list terminator and that resulted in
out-of-bound memory access. qemu_smbios_type11_opts also needs to have
an element for the type option.

..did not *have* the list terminator.., here and in 2/2.

Wow.  That's long ago..

This is a -stable material.
And since it's exactly the same 2 problems in 2 nearby places, it can
be combined into a single patch, but it definitely works this way too,
just a question of taste.
