[PATCH 2/4] Revert "sched/topology: Introduce for_each_numa_hop_mask()"

[Yury Norov]

Now that the only user of for_each_numa_hop_mask() is switched to using
cpumask_local_spread(), for_each_numa_hop_mask() is a dead code. Thus,
revert commit 06ac01721f7d ("sched/topology: Introduce
for_each_numa_hop_mask()").
