Yury Norov 97f3817039 sched/topology: Handle NUMA_NO_NODE in sched_numa_find_nth_cpu() ...

[ Upstream commit 9ecea9ae4d ]

sched_numa_find_nth_cpu() doesn't handle NUMA_NO_NODE properly, and
may crash kernel if passed with it. On the other hand, the only user
of sched_numa_find_nth_cpu() has to check NUMA_NO_NODE case explicitly.

It would be easier for users if this logic will get moved into
sched_numa_find_nth_cpu().
