[S390] Ensure that ipl panic notifier is called late.
The s390 ipl panic notifier will stop the system or trigger a system dump. This should be done as final action on the panic path. All other panic notifiers should be executed before. Currently we use priority 0 for the ipl notifier. In order to be called late, this patch changes the priority to INT_MIN which is the lowest possible priority.
