Previously for cyclic dma mode, once sdma fails sdma channel status will be set to DMA_ERROR, unless the transfer is prepared again, sdmac status will always be kept to DMA_ERROR, even the transfer for following buffers is successful. This patch updates sdmac status to the status of current buffer descriptor.
