iucv: fix cpu hotplug
If the iucv module is compiled in/loaded but no user is registered cpu hot remove doesn't work. Reason for that is that the iucv cpu hotplug notifier on CPU_DOWN_PREPARE checks if the iucv_buffer_cpumask would be empty after the corresponding bit would be cleared. However the bit was never set since iucv wasn't enable. That causes all cpu hot unplug operations to fail in this scenario. To fix this use iucv_path_table as an indicator wether iucv is enabled or not.
