gallium/radeon/gfx9: fix PBO texture uploads to compressed textures
st/mesa creates a surface that reinterprets the compressed blocks as RGBA16UI or RGBA32UI. We have to adjust width0 & height0 accordingly to avoid out-of-bounds memory accesses by CB. Cc: 17.1 <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
