netfilter: conntrack: split resolve_clash function
Followup patch will need a helper function with the 'clashing entries refer to the identical tuple in both directions' resolution logic. This patch will add another resolve_clash helper where loser_ct must not be added to the dying list because it will be inserted into the table. Therefore this also moves the stat counters and dying-list insertion of the losing ct. Signed-off-by: NFlorian Westphal <fw@strlen.de> Signed-off-by: NPablo Neira Ayuso <pablo@netfilter.org>
