driver core: Don't leak secondary fwnode on device removal
If device_add_property_set() is called for a device, a secondary fwnode is allocated and assigned to the device but currently not freed once the device is removed. This can be triggered on Apple Macs if a Thunderbolt device is plugged in on boot since Apple's NHI EFI driver sets a number of properties for that device which are leaked on unplug.
