To my concern, the nla_validate_deprecated, compared to nla_parse_deprecated,
will at lease save a memset in function nla_parse_deprecated

```
if (tb)
    memset(tb, 0, sizeof(struct nlattr *) * (maxtype + 1));
```

Morever, because the `nla_validate_deprecated` just validate the attributes
array and will not try to retrieve the nla pointers. It shall be faster
and cleaner here :D.
