Call ast when handling irq from userspace, otherwise we could miss
reschedule.  Right now arm_cpu_intr() does critical_exit() as the last
action, so the impact is not serious.

Remove duplicated interrupt disable in restore_registers macro, when
returning to usermode.  The do_ast macro disabled interrupts for us.
