Chris Wilson 014fc7abb7 dri: Disable page-flip between a tiled buffer and a linear scanout 
Keith Packard pointed out a loophole that could cause the DDX to end up
with a tiled scanout even if the user required a linear framebuffer;
that is by using page-flipping we could replace the scanout pixmap with
another of our choosing, and not necessarily tiled.

Close that loophole by only allowing an exchange of buffers between
identical tiling modes. For the common case, this is fine since they
will indeed be allocated with the same tiling. For the linear
framebuffer case with mesa using a tiled pixmap, we force it to blit
onto the scanout instead.
