MIPS: PCI: Fix pcibios_scan_bus() NULL check code path

Browse source

If pci_scan_root_bus() fails (ie returns NULL) pcibios_scan_bus() must
return immediately since the struct pci_bus pointer it returns is not valid
and cannot be used.

Move code checking the pci_scan_root_bus() return value to reinstate proper
pcibios_scanbus() error path behaviour.
