irqchip/irq-mbigen: Add of_node_put() before return
Each iteration of for_each_child_of_node puts the previous node, but
in the case of a return from the middle of the loop, there is no put,
thus causing a memory leak. Add an of_node_put before the return in
three places.
Issue found with Coccinelle.
