Eliminate the `kho_finalize()` function and its associated state from the KHO subsystem. The transition to a radix tree for memory tracking makes the explicit "finalize" state and its serialization step obsolete. Remove the `kho_finalize()` and `kho_finalized()` APIs and their stub implementations. Update KHO client code and the debugfs interface to no longer call or depend on the `kho_finalize()` mechanism. Complete the move towards a stateless KHO, simplifying the overall design by removing unnecessary state management.
