sched/cpufreq: Annotate cpufreq_update_util_data pointer with __rcu
Recently I added an RCU annotation check to rcu_assign_pointer(). All
pointers assigned to RCU protected data are to be annotated with __rcu
inorder to be able to use rcu_assign_pointer() similar to checks in
other RCU APIs.
This resulted in a sparse error:
kernel//sched/cpufreq.c:41:9: sparse: error: incompatible types in comparison expression (different address spaces)
Fix this by annotating cpufreq_update_util_data pointer with __rcu. This
will also help sparse catch any future RCU misuage bugs.
