Miaoqian Lin eff4780f83 irqchip/realtek-rtl: Fix refcount leak in map_interrupts ...

of_find_node_by_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in error path.
Call of_node_put() directly after of_property_read_u32() to cover
both normal path and error path.

Fixes: 9f3a0f34b8 ("irqchip: Add support for Realtek RTL838x/RTL839x interrupt controller")
