Subject: [PATCH 4.19 84/95] netfilter: ipset: Fix subcounter update skip

From: Phil Sutter <phil@....cc>

commit a164b95ad6055c50612795882f35e0efda1f1390 upstream.

If IPSET_FLAG_SKIP_SUBCOUNTER_UPDATE is set, user requested to not
update counters in sub sets. Therefore IPSET_FLAG_SKIP_COUNTER_UPDATE
must be set, not unset.

Fixes: 6e01781d1c80e ("netfilter: ipset: set match: add support to match the counters")
