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.
