r600: reset tex array override even when no view bound

If no view is bound we still should reset the override to 0
and array mode.

This should fix misrendering in firefox WebRender since
the pbo sampler was removed.

Fixes: 1250383e36 (st/mesa: remove sampler associated with buffer texture in pbo logic)
