The present do {} while stub's return cannot be checked, but the real
HOTPLUG_CPU=y implementation of register_hotcpu_notifier() is int-
returning. So let us make this stub consistent with the full version.
Redefining this as such will also help us remove some #ifdef-ery
elsewhere in kernel code, as shown in forthcoming patch.
