Joe Hattori 9322d1915f irqchip: Plug a OF node reference leak in platform_irqchip_probe() 
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.

Fixes: f8410e6265 ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")
