RPC flows are not reported in operational after OF channel restarts

This is only happening in Boron/Carbon, to reproduce:

• start mininet 1 switch.
• Push a flow via RPC or using OVS CLI so it does not show in operational.
• Check flow is in operational.
• Interrupt OF channel: sudo iptables -A OUTPUT -d 192.168.0.1 -j DROP
• Restore OF channel: sudo iptables -D OUTPUT -d 192.168.0.1 -j DROP
• Check flow is not in operational but it is in switch.
