    correct rcu_unlock_domain()
    
    Match rcu_lock_domain(), and remove the slightly misleading comment:
    This isn't just the companion to rcu_lock_domain_by_id() (and that
    latter function indeed also keeps the domain locked, not the domain
    list).
    
    No functional change, as rcu_read_{,un}lock() ignore their arguments
    anyway.
