Sergey Biryukov e5b586bfd0 Users: Correct the logic for switch_to_blog() in WP_User_Query::generate_cache_key().
If `$blog_id` equals `0`, it should be treated as the current site ID, and there is no need to switch to a different site.

This commit prevents an unnecessary call to `switch_to_blog()` on single site to avoid a fatal error when using `'orderby' => 'post_count'` and the deprecated `'who' => 'authors'` parameter:
{{{
Uncaught Error: Call to undefined function switch_to_blog() in wp-includes/class-wp-user-query.php:1077
}}}

Follow-up to [55657].
