KVM: do not call hardware_disable() on CPU_UP_CANCELED
When CPU_UP_CANCELED, hardware_enable() has not been called at the CPU which is going up because raw_notifier_call_chain(CPU_ONLINE) has not been called for this cpu. Drop the handling for CPU_UP_CANCELED. Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
