soc: rockchip: power-domain: fix err handle while probing

commit 1d961f11a108af9f7fbe89cc950a8d16ddbdbb28 upstream.

If we fail to probe the driver, we should not directly break
from the for_each_available_child_of_node since it calls of_node_get
while iterating. This patch add of_node_put to fix the unbalanced
call pair.
