iucv: fix kernel panic at reboot
The iucv base layer is initialized during the registration of the
first iucv handler. If no handler is registered and the
iucv_reboot_event() notifier is called, a missing check can cause
a kernel panic in iucv_block_cpu(). To solve this issue, check the
IRQ masks invoke iucv_block_cpu() for enabled CPUs only.
