spapr: Ensure CPU cores are added contiguously and removed in LIFO order
If CPU core addition or removal is allowed in random order leading to holes in the core id range (and hence in the cpu_index range), migration can fail as migration with holes in cpu_index range isn't yet handled correctly. Prevent this situation by enforcing the addition in contiguous order and removal in LIFO order so that we never end up with holes in cpu_index range.
