'wp_update_nav_menu' action returns inconsistent number of arguments

[barryceelen]

The 'wp_update_nav_menu' action is fired in two places with a different amount of arguments.

• wp-includes/nav-menu.php do_action( 'wp_update_nav_menu', $menu_id, $menu_data );
• wp-admin/includes/nav-menu.php do_action( 'wp_update_nav_menu', $nav_menu_selected_id );

The first one passes along the menu id and menu data, where the second one only returns the menu id.

@keraweb I know we discussed this in person, but can you refresh my memory on why the changes to the menu data were needed? Thanks!

@johnbillion Wow this is a while ago.
From what I see the attributes and array keys were inconsistent at two locations where the same action is used.

This fix makes it so that both locations where the action is used will pass the same parameters and take the same array keys while maintaining backwards compatibility with the original situation.
