Subject: [PATCH] media: rkvdec:Remove redundant memset
As dma_alloc_coherent() will return a zeroed buffer, we
don't need to memset the returned buffer.
priv_tbl = dma_alloc_coherent() and count_tbl = dma_alloc_coherent()
should be enough.
-see commit 750afb08ca71 ("cross-tree: phase out dma_zalloc_coherent()")
