irqchip: Plug a OF node reference leak in platform_irqchip_probe()
commit 9322d1915f9d976ee48c09d800fbd5169bc2ddcc upstream. platform_irqchip_probe() leaks a OF node when irq_init_cb() fails. Fix it by declaring par_np with the __free(device_node) cleanup construct. This bug was found by an experimental static analysis tool that I am developing.
