The HW DMA devices supported by IOAT driver do not transition to the "active" state until the first operation is started by the HW. Therefore, if the user calls "rte_dma_stop()" on a device without triggering any operations, the sequence of commands to be sent to the HW is different, as is the final device state.Update the IOAT driver "stop" function to take account of this difference.
