Suricata

Hi, everyone:

When I test a nfs pcap file, it make a segfault. Here's the detail.

It may test nfs with UDP protocol, but why crash in TcpSessionSetReassemblyDepth. This is very strange.

version info:
This is Suricata version 5.0.0 RELEASE
cargo 1.38.0 (23ef9a4ef 2019-08-20)
CentOS Linux release 7.6.1810 (Core)
Pcap file: nfsv2.pcap or https://wiki.wireshark.org/SampleCaptures?action=AttachFile&do=get&target=nfsv2.pcap.gz

May this report will help you to fix the bug.

Thanks and Regards.
