Codex:

Remove the `menu-item-has-children` class from bottom level menu items.

This runs on the {@see 'nav_menu_css_class'} filter. The $args and $depth parameters were added after the filter was originally introduced in WordPress 3.0.0 so this needs to allow for cases in which the filter is called without them.
