[U-Boot] [PATCH 2/3] usb: gadget: dwc2_udc_otg: fixed the error that the last packet transmission could not be terminated

[Frank Wang]

When the actual length is less than request length in the last request,
the data transmission should be terminated, because the packet
transmission have alreay finished.
