SRIOV PF got unbind instead of VF in case of IB link type

[heyvister1]

Fixing daemon sriov VFs config, where PF pci address got unbind instead of allegedly VF address, in case of using IB link type.

While sriov config is applied for VF devices by SriovNodePolicy, it appears that PF pci address got unbind insead of VF address. This has caused SRIOV initialization failure.
