PCI: hotplug: Remove unnecessary "dev->bus" test
Every pci_dev is on a valid pci_bus, so we don't need to test whether dev->bus is NULL or not. The only exceptions are a few legacy cases like alpha_core_agp_setup(), parisc_agp_setup(), and megaraid's make_local_pdev(), where we allocate a pci_dev with a NULL bus pointer. These are dubious uses (especially the megaraid one), and I don't think it's possible to exercise this pci_configure_slot() path with any of them. Found by Coverity (CID 146446).
