[PATCH net-next 2/3] ipset: drop ipset_nest_start() and ipset_nest_end()

From: Michal Kubecek
Date: Fri Apr 26 2019 - 05:13:17 EST


After the previous commit, both ipset_nest_start() and ipset_nest_end() are
just aliases for nla_nest_start() and nla_nest_end() so that there is no
need to keep them.
