PCI: fix wrong assumption in pci_common_swizzle

Current pci_common_swizzle() seems to have a assumption that
pci_bus->self is NULL on the pci root bus. But it might not be true on
some platforms. Because of this wrong assumption, pci_common_swizzle()
might cause endless loop. We must check pci_bus->parent instead.
