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 f46753c5 ("PCI: introduce pci_slot") and
d25b7c8d ("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]
