radeonsi: remove the NGG hack decreasing LDS usage to deal with overflows
The LDS size can't overflow anymore, so we can use the correct max LDS size. Fixes: a23802bcb9a - ac,radeonsi: start adding support for gfx10.3 Acked-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6137>
