i965/miptree: Delete MIPTREE_CREATE_LINEAR

This enum constant was introduced to enable blit maps with
intel_miptree_create da2880bea05bfc87109477ab026a7f5401fc8f0c. Now that
such maps use the more direct make_surface function which allows you to
specify the tiling directly, the constant is no longer being used.
