9b3a35ec8236933ab958a4c3ad883163f1ca66e7 virtio: verify that legacy support is not accidentally on
If a virtio device does not have legacy support, make sure that
it is actually off, and bail out if not.
For virtio-pci, this means that any device without legacy support
that has been specified to modern-only (or that has been forced
to it) will work.
For virtio-ccw, this duplicates the check that is currently done
prior to realization for any device that explicitly specified no
support for legacy.
This catches devices that have not been fenced properly.
