conntrack: timer reset in reply traffic causes performance impact
JIRA: SAMPLEVNF-44 The UDP connection timer was getting reset for every packets with reply traffic due to connection state check. This patch avoids resetting the timer instead uses the expected timeout to reset avoiding frequent timer reset for every packet.
