Flow eviction by datapath based on TCP states

Inactive TCP flows (flows that have already seen the closure cycle -
FIN/ACK or the RESET flags) should additionally be considered as a
free flow entry so that vRouter does not have to wait for agent to
accommodate new flows. This logic will provide better service under
severe occupancy. This modification also removes the previous logic
of trapping packets to agent when datapath detects closure of a TCP
stream.
