Cole Dishington c46308957f flow: optionally use pkt recursion for hash
If a Suricata inline IPS device is routing traffic over a
non-encrypted tunnel, like IPv6 tunnels, packets in a flow
will be dropped and not be matched. e.g.

The following example is a Suricata inline IPS with an IPv6 tunnel:
request: IPv4]ICMP] -> |IPS| -> IPv6]IPv4]ICMP]
reply:              <- |IPS| <- IPv6]IPv4]ICMP]
Both the IPv4 request and IPv6 reply will be seen by Suricata on
ingress. The flows will not be matched due to flow recursion level.

Optionally use pkt recursion level in flow hash. Excluding recursion
level in flow hash allows matching of packet flows and defrag on an
inline IPS Suricata scenario where the IPS device is a tunnel
terminator.
