That would work, but I don't like the idea of saying (in sysfs
device/sriov_totalvfs) "I have some VFs" only to say "not really, ha"
when someone tries to use them.  At least, not when we knew all along.

Let's look at this from a different angle:
If I posted a patch to make pci_sriov_set_totalvfs(dev, 0) do what I
want, would there be any objections to taking it?  It seems like a sane
API, the only existing (in-tree) users never pass 0, and it shouldn't
require too ugly an implementation.
