commit 487ad57ccfe1434e21774117d20dfd9e23f12afa

    Simplify REGISTRY cleanup usages
    
    In registry.c:registry_clear_data, the registered data is iterated and
    invoke each 'free' function with the data passed:
    
      for (registration = data_registry->registrations, i = 0;
           i < fields->num_data;
           registration = registration->next, i++)
        if (fields->data[i] != NULL && registration->data->free != NULL)
          adaptor (registration->data->free, container, fields->data[i]);
    
    we can see that data is passed to function 'free' and data is not NULL.
    In each usage, we don't have to get the data again through key and
    do NULL pointer checking.  This patch is to simplify them.
