Gadget driver should always use config_ep_by_speed() to initialize usb_ep struct according to usb device's operating speed. Otherwise, usb_ep struct may be wrong if usb devcie's operating speed is changed. The key point in this patch is that we want to make sure the desc pointer in usb_ep struct will be set to NULL when gadget is disconnected. This will force it to call config_ep_by_speed() to correctly initialize usb_ep struct based on the new operating speed when gadget is re-connected later.
