Thanks for catching this, Laura!

Actually, it is not strict enough. The function is used when handling
'add map' command. In bison, only counter, quota, limit and secmark are
allowed as stateful object "destination". I suspect ct helper is a
leftover from reusing the function somewhere else. I'll send a patch to
remove it.
