Previously, we allocated memory for image->plane[0].surface.isl.size
which is great if there is no compression. However, on BDW, we can do
CCS_D on X-tiled images so we also have to allocate space for the
auxiliary buffer. This fixes hangs in some of the WSI CTS tests and
should also reduce hangs in real applications. In particular, it fixes
the dEQP-VK.wsi.*.incremental_present.* test group.
When we hand the image off to X11 or Wayland, it will ignore the CCS
entirely which is ok because we do a resolve when it's transitioned to
VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.

Do we also need to return the size including the compressed buffer
further down this function?
Right now it's still : *size = image->planes[0].surface.isl.size;
.memoryTypeIndex = 0,
