    Bug 601512 -  Remove unnecessary check in GtkTreeModelFilter
    
    gtk_tree_model_filter_set_visible_func() is checking for
    priv->visible_func, but that is always going to be NULL since there's
    no way to call this function twice.
    
    Besides that the code itself is wrong, since it tries to call
    priv->visible_destroy without making sure that it's not NULL
