Seems better if it was called *get_next*_free_oem_inf?

This bit doesn't match what is described in the comment. It's also
incorrect for a few reasons:
- It should use windows_systemroot, instead of "/Windows"
- It doesn't handle case sensitive path stuff
Do we still need to check for the registry key? (I have no idea)

And this line seems like a bit of a hack. We have a place where
drivers are copied into the driverdir. I think it would be better if
we returned oem_inf from add_viostor_to_registry. But ...
Do we actually need to do this copy at all? The Red Hat drivers don't
require this, in order to boot (note that with the Red Hat drivers we
only half install them, they are properly installed when Windows
boots).
