[S390] irq: set __ARCH_IRQ_EXIT_IRQS_DISABLED Set __ARCH_IRQ_EXIT_IRQS_DISABLED in order to optimize irq_exit() a bit, since we call __do_softirq() instead of do_softirq(). This saves several needless checks, pointless interrupt disabling and an extra branch. If do_softirq() gets called from process context we still switch to the async stack.
