ACPI: NUMA: Optimize the check for the availability of node values

Browse Source 
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.

Use this return value to determine whether there are any available node
values in nodes_found_map, eliminating the need to use nodes_weight()
for this purpose.
