IPVS: Fallback if persistence engine fails
Fall back to normal persistence handling if the persistence
engine fails to recognise a packet.
This way, at least the packet will go somewhere.
It is envisaged that iptables could be used to block packets
such if this is not desired although nf_conntrack_sip would
likely need to be enhanced first.
