KVM: Tune hotplug/suspend IPIs
The hotplug IPIs can be called from the cpu on which we are currently running on, so use on_cpu(). Similarly, drop on_each_cpu() for the suspend/resume callbacks, as we're in atomic context here and only one cpu is up anyway. Signed-off-by: Avi Kivity <avi@qumranet.com>
