usb: gadget: udc: core: Document the relation between usb_ep_queue() and completion callback
Improve the kerneldoc for usb_ep_queue() to note explicitly that the
request's completion routine will be called if and only if the return
value is 0. The corresponding fact about usb_submit_urb() for the
host-side API has long been documented, and this has always been the
intention for the gadget API. But until now, documentation seems to
have been lacking.
