When doing XML-to-native conversion, addresses are not assigned.
The code building memballon device string assumed they are and
returned an error without reporting any error message, leading to:
error: An error occurred, but the cause is unknown
Assume that address type none means it's a PCI device, as we do
for other virtio devices.

This still leaves XML-to-native conversion broken for S390
machines, not just for memballon, but for other virtio devices
as well. Should we assign addresses in DomainXMLToNative as well,
or just decide which virtio device to add based on the machine type?
