proc: remove ifdef CONFIG_SPARSE_IRQ from stat.c
Impact: cleanup irq_desc can be NULL when CONFIG_SPARSE_IRQ=y only. therefore, NULL checking can move into kstat_irqs_cpu() of SPARSE_IRQ version. Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Acked-by: "Yinghai Lu" <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
