drm/radeon: Use kvmalloc for CS chunks
The number of chunks/chunks_array may be passed in
by userspace and can be large.
It has been observed to cause kcalloc failures from trinity fuzzy test:
WARNING: CPU: 0 PID: 5487 at mm/page_alloc.c:4385
__alloc_pages_nodemask+0x2d8/0x14d0
Obviously, the required order in this case is larger than MAX_ORDER.
So, just use kvmalloc instead.
