MINOR: protocol: directly call enable_listener() from protocol_enable_all()

protocol_enable_all() calls proto->enable_all() for all protocols,
which is always equal to enable_all_listeners() which in turn simply is
a generic loop calling enable_listener() always returning ERR_NONE. Let's
clean this madness by first calling enable_listener() directly from
protocol_enable_all().
