Subject: [PATCH v3 6/8] lib/cpumask: update comment to cpumask_local_spread()

Now that we have a for_each_numa_online_cpu(), which is a more
straightforward replacement to the cpumask_local_spread() when it comes to
enumeration of CPUs with respect to NUMA topology, it's worth to update the
comment.

  * There's a better alternative based on for_each()-like iterators:
  *
- *	for_each_numa_hop_mask(mask, node) {

  * It's simpler and more verbose than above. Complexity of iterator-based
  * enumeration is O(sched_domains_numa_levels * nr_cpu_ids), while
