    Allow the other nic to allocate VMs post PCI-PT VM creation.

    Let's say a compute node has got 2 network adapters
    (em1 and em2) with its correspondent VFs configured.
    If you start a VM with a direct-physical binding
    it will take one of these NICs.

    At that moment, SRIOV agent starts to show
    ERROR messages including the "device dictionary"
    completely empty.

    In consequence, you cannot allocate VMs with VFs
    even though there is still another NIC available.
