From: Mustafa Ismail <mustafa.ismail@intel.com>

Using PCI_FUNC macro in a VM, when the device is in passthrough
mode does not provide the real function instance. This means that
currently, devices will not probe unless the instance in the VM
matches the instance in the host.

Fix this by getting the pf_id from the LAN during the probe.
