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
