[Bug 1863441] Re: cmd_mode_sense always reports 0x70, no CDROM present

[John Snow]

Roger that, thanks!

I don't think we're very careful about which version we try to emulate.
In practice it's "Whatever seems to work across the largest swatch of
guest operating systems simultaneously".

If this comes up again, feel free to file against a specific guest OS
that appears to be non-functioning.

Thanks!
