netfilter: only warn once on wrong seqadj usage
Avoid potentially spamming the kernel log with WARN splash messages when catching wrong usage of seqadj, by simply using WARN_ONCE. This is a followup to commit db12cf274353 (netfilter: WARN about wrong usage of sequence number adjustments) Suggested-by: Flavio Leitner <fbl@redhat.com> Suggested-by: Daniel Borkmann <dborkman@redhat.com> Suggested-by: Florian Westphal <fw@strlen.de> Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
