    intel/blorp: Fix a couple asserts around image copy rectangles

    With dealing with rectangles in compressed images, you can have a width or
    height that isn't a multiple of the corresponding compression block
    dimension but only if that edge of your rectangle is on the edge of the
    image.  When we call convert_to_single_slice, it creates an 2-D image and a
    set of tile offsets into that image.  When detecting the right-edge and
    bottom-edge cases, we weren't including the tile offsets so the assert
    would misfire.  This caused crashes in a few UE4 demos
