 Fix sched_numa_find_nth_cpu() if mask offline
 
 sched_numa_find_nth_cpu() uses a bsearch to look for the 'closest'
 CPU in sched_domains_numa_masks and given cpus mask. However they
 might not intersect if all CPUs in the cpus mask are offline. bsearch
 will return NULL in that case, bail out instead of dereferencing a
 bogus pointer.
