Subject: [PATCH 27/39] netfilter: ipset: Remove redundant mtype_expire() arguments

From: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>

Remove redundant parameters nets_length and dsize, because
they can be get from other parameters.

Ported from a patch proposed by Sergey Popovich <popovich_sergei@...l.ua>.
