i965: Fix texture views of 2d array surfaces

It is legal to have a texture view of a single layer from a 2D array texture;
you can sample from it, or render to it. Intel hardware needs to be made aware
when it is using a 2d array surface in the surface state. The texture view is
just a 2d surface with the backing miptree actually being a 2d array surface.
This caused the previous code would not set the right bit in the surface state
since it wasn't considered an array texture.

I spotted this early on in debug but brushed it off because it is clearly not
needed on other platforms (since they all pass). I have no idea how this works
properly on other platforms (I think gen7 introduced the bit in the state, but I
am too lazy to check). As such, I have opted not to modify gen7, though I
believe the current code is wrong there as well.

Thanks to Chris for helping me debug this.

v2: Just use the underlying mt's target type to make the array determination.
This replaces a bug in the first patch which was incorrectly relying only
on non-zero depth (not sure how that had no failures). (Ilia)
