generic-ipi: Allow cpus not yet online to call smp_call_function with irqs disabled

Browse source

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.
