[Intel-gfx] [PATCH i-g-t] lib/rendercopy: Use gen8_wm_kernel__affine

[Chris Wilson]

The shaders/blit.g7a has weird artefacts (random pixel kill) when
drawing with to an odd destination coordinate. Rather than debug the
issue with the assembler, replace the kernel with the one used by SNA
for simple copies.
