Greg noticed that sriov_numvfs and sriov_drivers_autoprobe have
"unusual" permissions. These were added by:
0e7df22401a3 ("PCI: Add sysfs sriov_drivers_autoprobe to control VF driver binding")
1789382a72a5 ("PCI: SRIOV control and status via sysfs")
Kelsey's patch correctly preserves the existing permissions, but we
should double-check that they are the permissions they want, and
possibly add a comment about why they're different from the rest.
