Jann Horn cb361d8cde sched/fair: Use RCU accessors consistently for ->numa_group 
The old code used RCU annotations and accessors inconsistently for
->numa_group, which can lead to use-after-frees and NULL dereferences.

Let all accesses to ->numa_group use proper RCU helpers to prevent such
issues.
