This part reverts a commit from 2013. Something I would wager that will cause
multiple problems across the board.
If we look at the intel libva driver in particular, as-is this will cause all
get param queries on the render node to fail. Something that used to work
since render node support was introduced.
Analogously this will break the Intel Mesa driver when using the render node
and issuing the ioctls.
