crypto: ccp - Replace dma_pool_alloc + memset with dma_pool_zalloc
Use dma_pool_zalloc instead of using dma_pool_alloc to allocate memory and then zeroing it with memset 0. This simplifies the code. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Acked-by: Gary R Hook <gary.hook@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
