pci: Abort early if bus does not exist
When listing the devices on a PCI bus, the current code will blindly try to access all devices. Internally this causes pci_bus_to_hose() to be repeatedly called and output an error message every time. Prevent this by calling pci_bus_to_hose() once and abort early if no bus was found.
