Add a default goto table=94 for openvswitch fw
If enable explicitly_egress_direct=True and set port as
no security group and port_security=False, the ingress
flood will reappear. The pipleline is:
Ingress
table_0 -> table_60 -> NORMAL -> VM
Egress
table_0 -> ... -> table_94 -> output

Because ingress final action is normal, the br-int will learn the
source MAC, but egress final action is output. So VM's mac will
never be learnt by the br-int. Then ingress flood comes again.

This patch adds a default direct flow to table 94 during the
openflow security group init and explicitly_egress_direct=True, then
the pipleline will be:
Ingress
table_0 -> table_60 -> table_94 -> output VM
Egress
table_0 -> ... -> table_94 -> output

And this patch adds the flows coming from patch port which will
match local vlan then go to table 94 do the same direct actions.

Above flood issue will be addressed by these flows.
