The first_unset_node() function returns the first unused node in
nodes_found_map. If all nodes are in use, the function returns
MAX_NUMNODES. We can use this return value to determine whether there are
any available node values in nodes_found_map, eliminating the need to use
the nodes_weight() function to perform this check.
