  Log Message:
  ofproto-dpif-xlate: Prevent duplicating of traffic to a mirror port

Currently ofproto design disallow duplicating output packet on forwarding
and mirroring to/from same ovs port. Next scenario reveal lack of design:
1. Send ping between regular ovs ports (VFs, for ex.), stop it.
2. While rule still exist, make mirror for one of the ports.
Prevent duplicating of traffic to a mirror port.
