Kefeng Wang cddb536a73 irqchip/mbigen: Unify the error handling in mbigen_of_create_domain()
Dan Carpenter reported that commit fea087fc29 "irqchip/mbigen: move
to use bus_get_dev_root()" leads to the following Smatch static checker
warning:

	drivers/irqchip/irq-mbigen.c:258 mbigen_of_create_domain()
	error: potentially dereferencing uninitialized 'child'.

It should not cause a problem on real hardware, but better to fix the
warning, let's move the bus_get_dev_root() out of the loop, and unify
the error handling to silence it.
