    i965/miptree: Add an aux_disabled parameter to render_aux_usage

    Only one of the callers of intel_miptree_render_aux_usage actually took
    brw->draw_aux_buffer_disabled into account.  This was causing us to
    ignore draw_aux_buffer_disabled for the intel_miptree_prepare_render.
    This isn't a problem because the draw_aux_buffer_disabled entry was set
    during texture preparation and we already did the resolve at that time.
    However, this also meant that the aux_usage we were passing to
    brw_cache_flush_for_render and brw_render_cache_add_bo was wrong so our
    automatic cache flushing around aux_usage changes wasn't happening.
    This was causing GPU hangs in Oxenfree.
