sched/fair: Use recent_used_cpu to test p->cpus_ptr
When checking whether a recently used CPU can be a potential idle
candidate, recent_used_cpu should be used to test p->cpus_ptr as
p->recent_used_cpu is not equal to recent_used_cpu and candidate
decision is made based on recent_used_cpu here.
Fixes: 89aafd67f28c ("sched/fair: Use prev instead of new target as recent_used_cpu")
