Subject: [PATCH] hostip: drop guard from `Curl_resolver_error()` definition

To sync with its declaration.

Fixing (seen when building trurl in curl-for-win):
```
ld.lld: error: undefined symbol: Curl_resolver_error
```
Ref: https://github.com/curl/curl-for-win/actions/runs/23388349475/job/68038915761#step:3:7469

Closes #21054
