Enable MSI parent domain support in the x86 vector domain and fixup the checks in the iommu implementations to check whether device::msi::domain is the default MSI parent domain. That keeps the existing logic to protect e.g. devices behind VMD working. The interrupt remap PCI/MSI code still works because the underlying vector domain still provides the same functionality. None of the other x86 PCI/MSI, e.g. XEN and HyperV, implementations are affected either. They still work the same way both at the low level and the PCI/MSI implementations they provide.
