debugobjects: Free per CPU pool after CPU unplug
If a CPU is offlined the debug objects per CPU pool is not cleaned up. If
the CPU is never onlined again then the objects in the pool are wasted.
Add a CPU hotplug callback which is invoked after the CPU is dead to free
the pool.
[ tglx: Massaged changelog and added comment about remote access safety ]
