[mutter] backend/native: Remove unnecessary cursor renderer update

[Jonas Ådahl <jadahl src gnome org>]

    backend/native: Remove unnecessary cursor renderer update
    
    It is already handled by the monitor-updated-internal signal handler in
    meta-cursor-renderer-native.c, which will always be called indirectly
    by resuming the monitor manager.
    
    While at it, remove a useless comment.
