PCI/IOV: Add pci_iov_vf_id() to get VF index
The PCI core uses the VF index internally, often called the vf_id,
during the setup of the VF, eg pci_iov_add_virtfn().
This index is needed for device drivers that implement live migration
for their internal operations that configure/control their VFs.
Specifically, mlx5_vfio_pci driver that is introduced in coming patches
from this series needs it and not the bus/device/function which is
exposed today.
Add pci_iov_vf_id() which computes the vf_id by reversing the math that
was used to create the bus/device/function.
