(ITS#6154) response/cleanup callback mismatch

result.c:slap_send_search_entry() calls slap_cleanup_play() without having called slap_response_play() if backend_operational() failed.

This breaks back-relay's cleanup handler relay_back_swap_bd() - or rather, I suppose it makes that handler break cleanup handlers called after it. It restores op->o_bd from o_callback->sc_private, which was supposedly set by the o_callback->sc_response call.
