genirq: Add a kstat helper to increment irq stats
There is a common pattern all over the place:
kstat_incr_irqs_this_cpu(irq, irq_to_desc(irq));
This results in a call to core code anyway. So provide a function
which does the same thing in core.
While at it, replace the butt ugly macro with an inline.
