[PATCH tor v1 3/6] routerlist: Fix clang-15 complaint (unused variable)

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

clang-15 throws the following complaint:

```
  src/feature/nodelist/routerlist.c:246:7: error: variable 'nocache' set but not used [-Werror,-Wunused-but-set-variable]
    int nocache=0;
        ^
  1 error generated.
```

This variable firstly introduced in commit 3ad6dc0e2e91 ("r15806@catbus:
nickm | 2007-10-15 19:14:57 -0400"). Remove it.
