PCI: Refactor pci_bus_assign_domain_nr() for CONFIG_PCI_DOMAINS_GENERIC
Instead of assigning bus->domain_nr inside pci_bus_assign_domain_nr(),
return the domain and let the caller do the assignment. Rename
pci_bus_assign_domain_nr() to pci_bus_find_domain_nr() to reflect this.
No functional change intended.
