dnsdist: Fix 'warning: struct `UnusedStruct` is never constructed' warning

```
warning: struct `UnusedStruct` is never constructed
  --> src/lib.rs:10:8
   |
10 | struct UnusedStruct {}
   |        ^^^^^^^^^^^^
   |
   = note: `#[warn(dead_code)]` on by default
```

The warning that this struct was introduced to fix seems to be gone
anyway.
