r312686
    hyperv/hn: remove the MTU and IFF_DRV_RUNNING checking in hn_rxpkt()

    It's unnecessary because the upper nework stack does the same checking.

    In the case of Hyper-V SR-IOV, we need to remove the checking because
    1) multicast/broadcast packets are still received through the synthetic
    NIC and we need to inject the packets through the VF interface;
    2) we must inject the packets even if the synthetic NIC is down, or has
    a different MTU from the VF device.
