Jozsef Kadlecsik 7433b6d2af netfilter: ipset: Fix race between IPSET_CMD_CREATE and IPSET_CMD_SWAP 
Kyle Zeng reported that there is a race between IPSET_CMD_ADD and IPSET_CMD_SWAP
in netfilter/ip_set, which can lead to the invocation of `__ip_set_put` on a
wrong `set`, triggering the `BUG_ON(set->ref == 0);` check in it.

The race is caused by using the wrong reference counter, i.e. the ref counter instead
of ref_netlink.

Fixes: 24e227896b ("netfilter: ipset: Add schedule point in call_ad().")
