### Describe the bug

TL;DR: if you supply custom DNS `lookup` in 1.6+ and it fails with `ENOTFOUND`, `axios` throws `TypeError: address must be a string` instead

I supply custom DNS `lookup` to precisely control the timeout. I am using https://github.com/szmarczak/cacheable-lookup. It works correctly in axios before 1.6 but fails after because of this change:

When the callback returns the `err` as the first argument, the other two can be (and are) `undefined`. Axios 1.6+ attempts to resolve `family` and `address` regardless of `err` and trips over `undefined`.

Take a look:

### To Reproduce

Perform axios request against a domain that does not exists with a custom `lookup`. DNS `lookup` fails with `ENOTFOUND` but `axios` then fails with `TypeError: address must be a string`

### Code snippet

```js
// simplified test:


import CacheableLookup from 'cacheable-lookup';
import axios from 'axios';

const dns = new CacheableLookup({ resolver: new Resolver({ timeout: 200 }), maxTtl: 60 * 60, lookup: false });
const controller = new AbortController();

await axios.post('https://no-such-domain-987654.com', {}, {
  signal: controller.signal,
  lookup: dns.lookup.bind(dns),
});
```

### Expected behavior

`axios` should fail with the DNS `lookup` error, not the `TypeError`
