Introduce an *_dec_not_zero operation. ?Make this a special case of *_add_unless because batman-adv uses atomic_dec_not_zero in different places like re-broadcast queue or aggregation queue management. There are other non-final patches which may also want to use this macro.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
