dm: usb: Adjust usb_alloc_new_device() to return an error
This function returns NULL on error at present. Adjust it so that we can return a real error, as is needed with driver model. Also improve the error handling in its caller, usb_hub_port_connect_change(), and adjust the code order to prepare for driver model.
