speed up update_meta_cache with easy fix

[vladislavdavarashvili]

wp-includes/meta.php:1061

<?php
$meta_list = $wpdb->get_results( "SELECT $column, meta_key, meta_value FROM $table WHERE $column IN ($id_list) ORDER BY $id_column ASC", ARRAY_A );

in this request should avoid "ORDER BY $id_column ASC" to speed up this query (at least 3 times faster)
