[PATCH v2] usb: dwc3: gadget: Clear wait flag on dequeue

If an active transfer is dequeued, then the endpoint is freed to start a
new transfer. Make sure to clear the endpoint's transfer wait flag for
this case.

 Changes in v2:
 - Only clear the wait flag if the selected request is of an active transfer.
   Otherwise, any dequeue will change the endpoint's state even if it's for
   some random request.
