usb: dwc3: gadget: combine unaligned and zero flags
commit 1a22ec643580626f439c8583edafdcc73798f2fb upstream Both flags are used for the same purpose in dwc3: appending an extra TRB at the end to deal with controller requirements. By combining both flags into one, we make it clear that the situation is the same and that they should be treated equally.
