irq, fs/proc: replace loop with nr_irqs for proc/stat
Replace another nr_irqs loop to avoid the allocation of all sparse irq entries - use for_each_irq_desc instead. v2: make sure arch without GENERIC_HARDIRQS works too Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
