[PATCH] set cpu_state for CPU hotplug (ia64)
Dead CPU notifies online CPU that it's dead using cpu_state variable.
After switching to physical cpu hotplug, we forgot setting the variable.
This patch fixes it. Currently only __cpu_die uses it. We changed other
locations for consistency in case others use it.
