PCI: Remove unused pci_renumber_slot()
My philosophy is unused code is dead code. And dead code is subject to bit
rot and is a likely source of bugs. Use it or lose it.
This reverts part of f46753c5e354 ("PCI: introduce pci_slot") and
d25b7c8d6ba2 ("PCI: rename pci_update_slot_number to pci_renumber_slot"),
removing this interface:
pci_renumber_slot()
[bhelgaas: split to separate patch, add historical link from Alex]
