i965: Properly flush in hsw_pause_transform_feedback().
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!
