Hello! I see that this is the second time contributing to ntdll. Congrats!

In case you're not familiar with `UNICODE_STRING`, the `MaximumLength` should be at least `Length + 2`.

So I guess the correct code should read:

```suggestion:-0+0
    curdir.MaximumLength = max(curdir.Length + 2, MAX_PATH * sizeof(WCHAR));
```

However, I'm not sure if DOS paths longer than 260 characters are even valid. We need to test how Windows behaves in this case (does it truncate? does it use a short name? does it extend MaximumLength like you did?)
