Commit8c67d06f3f("usb: Link the ports to the connectors they are attached to") creates a link to the USB Type-C connector for every new port that is added when possible. If component_add() fails, usb_hub_create_port_device() prints a warning but does not unregister the device and does not return errors to the callers. Syzbot reported a "WARNING in component_del()". Fix this issue in usb_hub_create_port_device by calling device_unregister() and returning the errors from component_add().
