[libvirt PATCH 5/6] qemu: probe for "acpi-index" property

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

This property is exposed by QEMU on any PCI device, but we have to pick
some specific device(s) to probe it against. We expect that at least one
of the virtio devices will be present, so probe against them.
