    LinuxKPI: rcu: add optional condition to list_for_each_entry_rcu()
    
    list_for_each_entry_rcu() can take an optional condition.  Add the
    macro argument so code remains compiling but do not do anything with
    it just yet.
    
    Leave comments as list_for_each_entry_rcu() likely should have a
    different implementation.
