netfilter: conntrack: tell compiler to not inline nf_ct_resolve_clash
At this time compiler inlines it, but this code will not be executed under normal conditions. Also, no inlining allows to use "nf_ct_resolve_clash%return" perf probe. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
