FAILED: patch "[PATCH] xen-pciback: redo VF placement in the virtual topology" failed to apply to 5.4-stable tree

FAILED: patch "[PATCH] xen-pciback: redo VF placement in the virtual topology" failed to apply to 4.4-stable tree

The guest would still find the function at the original function number as long as __xen_pcibk_get_pci_dev() wouldn't be in sync. The same goes for AER wrt __xen_pcibk_get_pcifront_dev(). Undo overriding the function to zero and instead make sure that VFs at function zero remain alone in their slot. This has the added benefit of improving overall capacity, considering that there's only a total of 32 slots available right now (PCI segment and bus can both only ever be zero at present).
