arm64: fix a migrating irq bug when hotplug cpu
When cpu is disabled, all irqs will be migratged to another cpu. In some cases, a new affinity is different, the old affinity need to be updated and if irq_set_affinity's return value is IRQ_SET_MASK_OK_DONE, the old affinity can not be updated. Fix it by using irq_do_set_affinity. And migrating interrupts is a core code matter, so use the generic function irq_migrate_all_off_this_cpu() to migrate interrupts in kernel/irq/migration.c.
