Fixes a number of transform feedback tests when run with Linux 4.8, which allows us to use the MI_LOAD_REGISTER_REG command, at which point we started using this new broken path.
ES3-CTS.functional.transform_feedback.array_element.interleaved.lines.* and Piglit's arb_transform_feedback2/draw-auto are both fixed by this patch, for example. Thanks to Chris Wilson for catching this mistake!
