Comment 32 for bug 1832915

Since this is constructed like:
  ADD_ID_TO_LIST(node[0].node_id, target_node_list_p);
I guess this delivers 0 and then 8 in my system
== the node_id instead of the index.

1796 if (ID_IS_IN_LIST(ix, p->node_list_p)) {
1797 proc_avg_node_CPUs_free += node[ix].CPUs_free;
1798 }

While the indexes are 0, 1

I think we'd want to convert our node_id->array-index mapper to a function and use it in the place we fixed first and this one. To then retest this.
