    Prevent multiple datanetworks to same interface

    Since sriov-network-device-plugin upgrade to v3.5.1, assigning multiple
    datanetworks to the same interface is not possible anymore.

    This change restricts the system interface-datanetwork-assign command to
    prevent that from happening.

    Test Plan:
    PASS: assign datanetwork1 to sriov0 interface: ok
    PASS: assign datanetwork2 to same sriov0 interface: fails
    PASS: create new vf0 interface on top of sriov0: ok
    PASS: assign datanetwork1 to vf0: ok
    PASS: assign datanetwork2 to vf0: fails
    PASS: create new vf1 interface on top of sriov0: ok
    PASS: assign datanetwork2 to vf1: ok
    PASS: assign datanetwork1 to vf1: fails
