Subject: [PATCH] hostip: fix unreachable code in rare build configuration

with cmake options:
```
-DCMAKE_UNITY_BUILD=OFF -DCURL_DISABLE_HTTP=ON -DENABLE_THREADED_RESOLVER=OFF
```

Fixing (seen with Apple clang 17):
```
lib/hostip.c:939:16: error: code will never be executed [-Werror,-Wunreachable-code]
  940 |       *entry = dns;
      |                ^~~
```

Closes #20344
