Description

Getting
Assertion failed: (!((state->curr_tx == ((void*)0)))), function SMTPTransactionComplete, file app-layer-smtp.c, line 887.

Reproducer is suricata -r lola.pcap -c suricata.yaml -k none
Need to craft a Suricata-verify test out of this
The pcap comes from S-V test smtp-rset
+ fuzzpcap tcptofpc.py
+ easy hex editing to have multiple RSET in one packet
+ add a packet starting a command but not ending it (ie no end of line)
+ easy hex editing to have multiple 250 in different packets
+ fuzzpcap back to pcap

Found by CIFuzz in https://github.com/OISF/suricata/pull/6751
Not found by oss-fuzz even if it seems reachable by fuzz_sigpcap_aware...
