malloc_simple: calloc: don't call memset if malloc failed
malloc_simple() can return 0 if out of memory. Don't call memset from calloc() in this case but rely on the caller checking the return value. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Marek Vasut <marex@denx.de>
