Remove even more unused local variables

[Latz]

There are several local variables in "comment-template.php" which aren't used anymore.

In 36343:

Comments: Remove unused $default_comments_page variable in get_comment_link().

Left in r34735, fetches the default_comments_page option twice since this variable is unused.

See #34073 and #35511.

Props Latz.

@Latz The comments_template() function is tricky because the variables set may be used in your theme's comments.php file. Example: I can see $comment_author_url used in theme-compat/comments.php.

Before any of the globals or local variables are removed from comments_template() some research and testing will need to be done across the theme directory.

Replying to rachelbaker:

I have to admit that I hadn't thought that far. Will take a look but it at first sight it seems like a strange programming style.

Closing this since the unused variable that can be cleaned up at this time was done in r36343. @Latz feel free to open a new ticket as needed.
