Suricata

I use trex v2.97 to test suricata v7.0.2 and found some problems.

1. The tcp.active_sessions and flow.active count in stats.log will never reduce to zero after trex stop.

The trex command:

./t-rex-64 -f cap2/many_client_example.yaml -d 300 -p -m 30000

2. Sometimes the tcp.active_sessions will be a very big number at startup, looks like the int has overflow.
