lib/test_cpumask: fix cpu_possible_mask last test
Since cpumask_first() on the cpu_possible_mask must return at most nr_cpu_ids - 1 for a valid result, cpumask_last() cannot return anything larger than this value. As test_cpumask_weight() also verifies that the total weight of cpu_possible_mask must equal nr_cpu_ids, the last bit set in this mask must be at nr_cpu_ids - 1.
