KAMEZAWA Hiroyuki 73e753a50d CPU HOTPLUG: avoid hotadd when proper possible_map isn't specified ...

cpu-hot-add should be fail if cpu is not set in cpu_possible_map.  If go
ahead, the system will panic soon.

Especially, arch which requires additional_cpus= parameter should handle
this.  Tested on ia64.
