    Don't validate local_link_connection when port has client-id

    Infiniband ports do not require the local_link_connection field to be
    populated as the network topology is discoverable by the Infiniband
    Subnet Manager.

    This change removes the requirement for local_link_connection for
    Infiniband ports. Infiniband ports have a client-id in their extra
    field.
