Maybe it's the FreeBSD implementation that needs to be adjusted then, 
because none of those functions are valid on FreeBSD, and the 
documentation for VFIO functions explicitly mentions that on FreeBSD, 
they should return an error. I went with adjusting Linux implementation 
to minimize the amount of changes we have to make (and only change code 
path that no one uses in the first place), but maybe that was a wrong 
decision.

I'm not sure if changing the API return value to match what was 
documented counts as an API change, so maybe backport to stable is not 
advised here.
