dmaengine: imx-sdma: Remove call to memset after dma_alloc_coherent

In commit 518a2f1 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed. Signed-off-by: Fuqian Huang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Vinod Koul <[email protected]>
