Currently the status of the request being completed comes from the dwc3_event_depevt status. The resulting status will then be applied to the request on dwc3_gadget_del_and_unmap_request. This assigned status is not right in every case. Since it is possible that more requests can be ready on the interrupt handler we have to set the actual status for every request from the trbstatus instead.
