usb: dwc3: gadget: Don't clear flags before transfer ended
commit a114c4ca64bd522aec1790c7e5c60c882f699d8f upstream.
We track END_TRANSFER command completion. Don't clear transfer
started/ended flag prematurely. Otherwise, we'd run into the problem
with restarting transfer before END_TRANSFER command finishes.
