usb: gadget: Refactor request completion
Use the recently introduced usb_gadget_giveback_request() in favor of direct invocation of the completion routine. All places in drivers/usb/ matching "[-.]complete(" were replaced with a call to usb_gadget_giveback_request(). This was compile-tested with all ARM drivers enabled and runtime-tested for musb.
