gpio: Fix potential NULL handler data in chained irqchip handlergpio-v3.17-4
There is possibility with misconfigured pins that interrupt occurs instantly after setting irq_set_chained_handler() in gpiochip_set_chained_irqchip(). Now if handler gets called before irq_set_handler_data() the handler gets NULL handler data. Fix this by moving irq_set_handler_data() call before irq_set_chained_handler() in gpiochip_set_chained_irqchip().
