[S390] Fix cpu hotplug (missing 'online' attribute).
72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverts the logic if an 'online' attribute in /sys/devices/system/cpu/cpuX should appear. So we end up with no hotpluggable cpus at all... Set the hotpluggable value to one to make sure the online attribute appears again. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
