SMP: make IPI fatal code unique
The same smp fatal code is used in percpu
_Per_CPU_State_change(). In order to determine which CPU
requested a fatal shutdown and which CPU responds to it a
unique code should be used.
A unique code makes it also possible to handle the CPUs
differently in the fatal exception handler.
