utils_curl_stats: Drop the nonnull attribute from curl_stats_from_config.

It's not overly useful after all but generates false compiler warnings /
errors on Xenial using CLANG, since we also check the parameter in the
function (which is what we want in the end and there's no risk in actually
calling it with a NULL value).
