i915,i830: Remove dead HiZ assertions in *update_draw_buffer()

i915 and i830 hardware doesn't have HiZ, so remove all HiZ related
assertions from *update_draw_buffer().

I've removed the dead format checks completely rather than replace them
with more appropriate checks. This doesn't reduce "assertion coverage",
however, because when I added these HiZ related assertions in c8fdf66
there were no pre-existing checks there.
