Message:

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].

Props dd32, austinginder, RavanH, mukesh27.
Fixes #59011.
