Strictly speaking the right thing todo would be to have a method called
before starting the guest, which  populates the disk->info.addr based
on disk->dst, if the user hasn't already provided that info. Then this
particularly code here would be unchanged. eg something needs to be
calling virDomainDiskDefAssignAddress
