Changes to the checkbox already change the Controller to Virtio SCSI
(single), regardless of what was selected before. Anyways, the automatic
change only happens in the wizard.
In case that a user wants iothread with a controller other than SCSI
single or on a single disk, they can change that in the VM config, but I
don't think that this is a common problem, at least much less common
than wanting iothread enabled per default.
But I guess we can show a warning instead.
