amd/common: round cube array slice in ac_prepare_cube_coords
The NIR-to-LLVM pass already does this; now the same fix covers radeonsi as well. Fixes various tests of dEQP-GLES31.functional.texture.filtering.cube_array.combinations.* Cc: mesa-stable@lists.freedesktop.org Reviewed-by: Marek Olšák <marek.olsak@amd.com> Reviewed-by: Dave Airlie <airlied@redhat.com>
