 The r38446 have removed a direct SQL query and replaced it by
 `get_comments` call. Just the `$_where` variable, which was used for
 building the direct SQL query was not removed.

 Since it's not being used elsewhere in the code, it should be removed in
 order to improve the readability of the code.
