genirq/proc: Simplify irqdesc::kstat_irqs handling further

Browse source

Interrupts which have no action and chained interrupts can be
ignored due to the following reasons (as per tglx's comment):

  1) Interrupts which have no action are completely uninteresting as
     there is no real information attached.

  2) Chained interrupts do not have a count at all.

So there is no point to evaluate the number of accounted interrupts before
checking for non-requested or chained interrupts.

Remove the any_count logic and simply check whether the interrupt
descriptor has the kstat_irqs member populated.
