[PATCH] PCI: Export pci_probe_reset_function()

[Alex Williamson <alex.williamson@redhat.com>]

The equivalent bus and slot versions of this are already exported and
vfio-pci would like a function-probe available so we can expose
function-level reset capabilities to the user without necessarily
using it to perform a reset before enabling the device for the user.
