[Stable-8.2.2 24/60] hw/smbios: Fix OEM strings table option validation

[Michael Tokarev]

From: Akihiko Odaki <akihiko.od...@daynix.com>

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

Fixes: 2d6dcbf93fb0 ("smbios: support setting OEM strings table")
