    Check for unbound ports in L3 RPC handler

    The handler was making the incorrect assumption that once a
    host_id was set, a port which failed to bind could only be in
    the 'binding_failed' state. So it would not try to rebind ports
    that encountered an exeption during port binding commit that left
    them in the unbound state.
