refactor(linter): dereference IDs as soon as possible (#6821)

Browse source 
Style nit. Dereference `&ScopeId` to `ScopeId` (and other IDs) as early as possible. `&ScopeId` is 8 bytes, whereas `ScopeId` is 4 bytes.

In simple cases like these, compiler will optimize it anyway, but still I think it's a better pattern to dererence early. In more complicated cases, it will be better for performance, and in my opinion, it makes things clearer if vars called `scope_id` are always a `ScopeId`, not sometimes a `&ScopeId`.
