Description

When I start Suricata and process a PCAP file with 0 packets, the process hangs and quits:

*start suricata*

> suricatasc -c "pcap-file /tmp/packets_no.pcap /tmp/" 
< {"message": "Successfully added file to list", "return": "OK"}

> suricatasc -c pcap-file-list
*no response, process is stuck for 1 minute and then quits with error*

If I start Suricata and process some normal PCAP file first, and later send a PCAP file with 0 packets, it is handled fine and creates an empty report file.

*start suricata*

> suricatasc -c "pcap-file /tmp/packets_yes.pcap /tmp/a/" 
< {"message": "Successfully added file to list", "return": "OK"}

> suricatasc -c "pcap-file /tmp/packets_no.pcap /tmp/b/" 
< {"message": "Successfully added file to list", "return": "OK"}

> suricatasc -c "pcap-file-list" 
< {"message": {"count": 0, "files": []}, "return": "OK"}

* eve.json was written for each PCAP file and suricata process is fine *

Expected behavior:
Scanning a 0-packet PCAP file produces an empty report with no errors.

Actual behavior:
Scanning a 0-packet PCAP file as the first file to a new Suricata process hangs and then quits with error.
