sched: Better name for for_each_domain_rd
As suggested by Peter Ziljstra, make better choice of name
for for_each_domain_rd(), containing "rcu_dereference", given
that it is but a wrapper for rcu_dereference_check(). The name
rcu_dereference_check_sched_domain() does that and provides a
separate per-subsystem name space.
