Comments: Add back `$req` variable in `comments_template()`.

The variables in `comments_template()` should never be assumed to be unused. This function includes the `comments.php` template file from the active theme or falls back to `theme-compat/comments.php`. This is why including a file within a function only brings pain and sorrow.
