The return of the present "do {} while" based stub definition of
register_hotcpu_notifier() cannot be checked. This makes the stub
asymmetric w.r.t. the real HOTPLUG_CPU=y implementation that is
int-returning. So let us redefine this to be consistent with the full
version. Also do the same for unregister_hotcpu_notifier().
We cannot define these as static inline functions due to an existing GCC
bug (#33172). So define as macros that return appropriately instead (int
'0' for the register_hotcpu_notifier case and void for
unregister_hotcpu_notifier).
