MU PLUGIN DIR path is incorrect

plugin_dir_url(__DIR__) gives an odd value

 plugin_dir_url(__DIR__);
http://watchteam.org/wp-content/plugins/var/www/

Which leads to

https://vps.org/wp-content/mu-plugins/a3-lazy-load/admin/includes/uploader/uploader.css  
  
https://pod.org/wp-content/plugins/var/www/wp-content-mount/mu-plugins/a3-lazy-load/admin/includes/uploader/uploader.css
