Don't allow the learning switch to send packets back out the incoming port.

The learning switch functionality included in OpenFlow will send packets
out the port they arrived on if the learned destination is from that port.
This causes problems when newer switches flood packets for destinations they
don't know and OpenFlow reinjects packets back into the network.  The correct
behavior is to just drop the packet.
