http: fix `-Wunreachable-code` in !websockets !unity builds

Also requires non-unity build. Possibly more non-default options are
necessary to reproduce. Seen with llvm/clang.

```
lib/http.c:1856:15: error: code will never be executed [-Werror,-Wunreachable-code]
 1856 |     httpreq = HTTPREQ_GET;
      |               ^~~~~~~~~~~
1 error generated.
```

Closes #19275
