detect/geoip: do not require packet

Ticket: 8333

Allows to pass on pseudo packets

So, that a ruleset like
pass ssh any any -> any any (geoip:any,US,IN; sid: 1;)
drop ip any any -> any any (flow:established, to_server; sid:2;)

Does not lead to a drop on the pseudo-packet when we flush
because ssh traffic gets encrypted
