Probably a leftover of a time when slap_known_controls was a pointer

two possibilities:
a) ignore it: cleanup could occur too late, when response has already
been returned to client; in this case a return code is there only
because of the standard API
b) handle it: cleanup return code could be usefully returned to caller
if (a), then the return code can be safely ignored

There should be no impact, since they're both limited to 0,999
