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.

Isn't there a place where a default definition of this can be
defined? Instead of adding it separately to every architecture.

Not that I would know about such a place - and all other atomic* macro 
definitions also suggest that there is no such place.

Kind regards,
