The documentation states:
``iothread``
Supported for controller type ``scsi`` using model ``virtio-scsi`` for
``address`` types ``pci`` and ``ccw`` :since:`since 1.3.5 (QEMU 2.4)`. The
The code itself didn't validate if iothread is specified for any other
controller type.
Add test case showing the issue on one example.
