Remove Unused variable

[adnan.limdi]

<?php
1625    $comments = $wpdb->get_results(
                "SELECT `comment_ID` FROM `{$wpdb->comments}`
                        WHERE `comment_date_gmt` > '2015-04-26'
                        AND LENGTH( `comment_content` ) >= {$allowed_length}
                        AND ( `comment_content` LIKE '%<%' OR `comment_content` LIKE '%>%' )"
        );

Also I See This here date is define static : WHERE comment_date_gmt > '2015-04-26' so we need to update this for future version.

Thanks for the patch. The unused variable can be removed, but the date is specific to the security fix in [32308], there's no need to update it in a future version.
