usb: dwc3: gadget: Return success always for kick transfer in ep queue
commit 18ffa98 upstream. If an error is received when issuing a start or update transfer command, the error handler will stop all active requests (including the current USB request), and call dwc3_gadget_giveback() to notify function drivers of the requests which have been stopped. Avoid returning an error for kick transfer during EP queue, to remove duplicate cleanup operations on the request being queued.
