intel-iommu: Handle PCI domains appropriately.
We were comparing {bus,devfn} and assuming that a match meant it was the same device. It doesn't -- the same {bus,devfn} can exist in multiple PCI domains. Include domain number in device identification (and call it 'segment' in most places, because there's already a lot of references to 'domain' which means something else, and this code is infected with ACPI thinking already).
