linux57-tkg: The execution of finish_cpu when offlining cores introduced with https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bf2c59fce4074e55d622089b34be3a6bc95484fb breaks suspend on our CPU schedulers. Skipping the call to fallback to idle_task_exit fixes it.

There are other issues regarding suspend upstream but that should cover our side of the coin.
