I'm not positive about this, but pci_disable_device() should be called
as part of the device's driver's .remove method, which is called from
the sequence:

hotplug driver ->
    pci_remove_bus_device() ->
        pci_destroy_dev() ->
            pci_stop_dev() ->
                device_unregister()
