The End Transfer command from a stream endpoint will generate a NoStream event, and we should ignore it. Currently we set the flag DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command, and it will be cleared on the next stream event. However, a stream event may be generated before the End Transfer command completion and prematurely clear the flag. Fix this by setting the flag on End Transfer completion instead.
