padata: Fix fallout from get_online_cpus() rework
The rework of the cpu hotplug locking missed to remove a put_online_cpus()
call and to convert the hotplug state registration to the cpuslocked()
version. Fix it up.
Fixes: bbd8797975ce ("padata: Avoid nested calls to get_online_cpus() in pcrypt_init_padata()")
