Subject: [PATCH v2 6/6] sched: Annotate perf_domain pointer with __rcu

This fixes the following sparse errors in sched/fair.c:

fair.c:6506:14: error: incompatible types in comparison expression
fair.c:8642:21: error: incompatible types in comparison expression

Using __rcu will also help sparse catch any future bugs.
