I suppose we could add require_gem to open_driver_render(), but it
doesn't seem that generic. We definitely can do KMS operations even if
execbuf() returns -EIO.

At some point, we'll just have to bite the bullet and start rewriting
GEM tests to apply to amdgpu as well -- there are quite a few that I
think aren't i915 centric, e.g. gem_sync, that might help define what we
can and what we can't generalise.
