sched/topology: Fix sched_numa_find_nth_cpu() in non-NUMA case
When CONFIG_NUMA is enabled, sched_numa_find_nth_cpu() searches for a
CPU in sched_domains_numa_masks. The masks includes only online CPUs,
so effectively offline CPUs are skipped.
When CONFIG_NUMA is disabled, the fallback function should be consistent.
Fixes: cd7f55359c90 ("sched: add sched_numa_find_nth_cpu()")
