The "isapc" machine only provides an ISA bus, not a PCI one, and doesn't instanciate any i440FX south bridge. Its machine class defines PCMachineClass::pci_enabled = false, and pc_init1() only uses the pci_type argument when pci_enabled is true. Since for this machine the argument is not used, passing NULL makes more sense.
