IB/mthca: Use zeroing memory allocator than allocator/memset
Use dma_zalloc_coherent for allocating zeroed memory and remove unnecessary memset function. Done using Coccinelle. Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci 0-day tested with no failures. Suggested-by: Luis R. Rodriguez <mcgrof@kernel.org> Signed-off-by: Himanshu Jha <himanshujha199640@gmail.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
