iommu/vt-d: Fix compile error with CONFIG_PCI_ATS not set
Fix the compile error below (CONFIG_PCI_ATS not set):

drivers/iommu/intel/dmar.c: In function ‘vf_inherit_msi_domain’:
drivers/iommu/intel/dmar.c:338:59: error: ‘struct pci_dev’ has no member named ‘physfn’; did you mean ‘is_physfn’?
  338 |  dev_set_msi_domain(&pdev->dev, dev_get_msi_domain(&pdev->physfn->dev));
      |                                                           ^~~~~~
      |                                                           is_physfn
