This feels like to much automagic to me, because changes to the checkbox
(even if checkbox is for a virtio disk) will change the controller type
and vice versa. This also makes it impossible to only set iothread on
certain disks or use the "Virtio SCSI single" controller type without
setting iothread.

Is it possible to instead have the checkbox be invalid with an
appropriate error for the user when it's a bad configuration?
