get_comment_link without pagination base in the returned URL?

It’s strange that you want to use comments pagination where the comment links are without the comments pagination base.

But you can try this (untested):

/**
 * Remove the comments pagination base from comments links
 */

! is_admin() && add_filter( 'get_comment_link', function( $link, $comment, $args )
{ 
    if( $args['per_page'] )
        $link = sprintf( "%s#comment-%d",
            get_permalink( $comment->comment_post_ID ),
            $comment->comment_ID
        );
    return $link;
}, 10, 3 );

Another option would be to replace it with something like:

$link = preg_replace( '%comment-page-\d+/%', '', $link );

where the base could be dynamically fetched with:

global $wp_rewrite;
if ( $wp_rewrite->using_permalinks() )
    $comments_pag_base = $wp_rewrite->comments_pagination_base;
