Suricata

Environment
- Suricata 8.0.2 + nDPI 4.14
- AArch64 / NixOS

After applying the fix from https://github.com/OISF/suricata/pull/14847, Suricata still crashes with SIGSEGV in StorageGetById. The crash now occurs in OnFlowUpdate and potentially in EveCallback, rather than in DetectnDPIProtocolPacketMatch.

https://github.com/OISF/suricata/pull/14847 fixed the NULL p->flow case, however there are additional crash paths where the flow exists but f->storage is NULL.

I have a branch with a fix addressing all cases: https://github.com/antoineaboufayssal/suricata/tree/ndpi/v3. I can open a PR for it if you want.

(sorry you guys must hate me, 2 ndpi bugs in 1 week)
