cpu/hotplug: Remove unused but set variable in _cpu_down()

After the recent removal of the hotplug notifiers the variable 'hasdied' in _cpu_down() is set but no longer read, leading to the following GCC warning when building with 'make W=1': kernel/cpu.c:767:7: warning: variable ‘hasdied’ set but not used [-Wunused-but-set-variable] Fix it by removing the variable.
