Subject: [PATCH net 1/5] netfilter: nf_conntrack_netbios_ns: fix helper module alias

From: Florian Westphal <fw@...len.de>

The helper gets registered as 'netbios-ns', not netbios_ns.
Intentionally not adding a fixes-tag because i don't want this to go to
stable. This wasn't noticed for a very long time so no so no need to risk
regressions.
