commit fbf33f516b upstream.
Commit 4f535093cf "PCI: Put pci_dev in device tree as early as possible"
moves device registering from pci_bus_add_devices() to pci_device_add().
That causes problems for virtual functions because device_add(&virtfn->dev)
is called before setting the virtfn->is_virtfn flag, which then causes Xen
to report PCI virtual functions as PCI physical functions.
Fix it by setting virtfn->is_virtfn before calling pci_device_add().
[Jiang Liu]: Move the setting of virtfn->is_virtfn ahead further for better
readability and modify changelog.
