Check whether the disable-legacy property is present on the following
devices:
virtio-balloon-pci
virtio-blk-pci
virtio-scsi-pci
virtio-net-pci
virtio-gpu-pci
Assuming that if QEMU knows other virtio devices where this property
is applicable, it will have at least one of these devices.
Added in QEMU by:
commit e266d421490e0ae83044bbebb209b2d3650c0ba6
virtio-pci: add flags to enable/disable legacy/modern
