Fixes #256
This PR fixes a crash that occurred in the Wireshark GUI when using Follow -> TCP Stream with the JA4 plugin installed.
Root cause:
display_hashes_from_packet_table()could attempt to add fields under an invalid or incomplete subtree. When the GUI later traversed this subtree (e.g. during stream follow), Wireshark crashed.Verification:
wireshark -r http1.pcapng-> no crash on Follow TCP Streamtshark(it doesn’t access GUI display-tree paths)
