dwc3: gadget: Fix list corruption issue with dequeue API
dwc3_ep_dequeue() API does wait for completion of request after
releasing spinlock, and reacquire same spinlock on getting unblock.
Here there is possibility that request may have been completed
itself and removed from started_list (dwc3_gadget_giveback() may
already completed). Hence if req->trb is NULL, don't try to call
dwc3_gadget_giveback() API which tries to delete request from
started_list which results into list corruption.
