MLK-23181-3 usb: cdns3: gadget: handle multiple trb request properly

We use polling EP_TRADDR to judge if the trb has finished, so for
request which includes multiple trb, we may quit the trb judgement
in the middle of request, in that case, we can't giveback the
request. We should only giveback the request when all the TRB in
this request has finished.
