generic-ipi: Allow cpus not yet online to call smp_call_function with irqs disabled
Because of deadlock possiblities smp_call_function() is not allowed to be called with interrupts disabled. Add an exception for the cpu not yet online, as no one else can send smp call function interrupt to this cpu that is not yet online and as such deadlock condition is not possible.
