conntrack: Fix to avoid duplicate connections in initial burst
JIRA: SAMPLEVNF-43
Before connection setup, if there are multiple packets in the burst
and are belongs to same connection, it was adding new connection for
the same 5 tuple connection, leading to multiple connections in the CT.
It was causing more number of active connections than possible.
