[2.1-Build 40] Service chaining with Multi Service instances is not working

[Daisuke Nakajima]

Service chaining with Multi Service instances is not working, even though Single service instance is working.

Test env
 VM1 --- SI1 --- SI2 --- VM2.

VM2(50.0.0.5) sends ICMP to VM2(200.0.0.5) , the ICMP echo requests can reach VM1. SC1 receaves ICMP echo reply from VM1 and forwards them, however vRouter drops the packet.

Service instance1:
root@sc1:~# tcpdump -ni eth1 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
