dmaengine: use DMA_COMPLETE for dma completion status
the DMA_SUCCESS is a misnomer as dmaengine indicates the transfer is complete and gives no guarantee of the transfer success. Hence we should use DMA_COMPLTE instead of DMA_SUCCESS Acked-by: Dan Williams <dan.j.williams@intel.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
