Kbuild test robot found we passed a pci_dev * to
pci_domain_nr(). In old IA64 specific pci_domain_nr()
It was macro defines:
#define PCI_CONTROLLER(busdev) ((struct pci_controller *) busdev->sysdata)
#define pci_domain_nr(busdev) (PCI_CONTROLLER(busdev)->segment)
Both pci_dev * and pci_bus * have opaque sysdata, so IA64 specific
pci_domain_nr() could get the pci_controller and return the exact
domain number, but now we use common pci_domain_nr() functions, so we
should fix this warning.
