The USB CDROM functionality is currently broken and the patch handles
just that, like the SD card workaround (qemuDiskBusIsSD). The whole
patch is

 src/qemu/qemu_command.c
 src/qemu/qemu_command.h
 src/qemu/qemu_domain.c
 tests/qemuxml2argvdata/disk-cdrom-bus-other.x86_64-latest.arg

I offered my simple fix and don't have the time to implement the
proposed -blockdev based solution, after investigating Gerd's
alternative suggestion for the alternate fix.

That's it, no harm intended.

P.S. also, because currently the additional (probably QEMU / edk2) bugs
won't let me fix my LibreOffice build at this state anyway, so it seems
I'm far away from a working environment to fix my real problem.
