platform/surface: aggregator: Add missing fwnode_handle_put()
[ Upstream commit acd0acb802b90f88d19ad4337183e44fd0f77c50 ]
In fwnode_for_each_child_node(), we should add
fwnode_handle_put() when break out of the iteration
fwnode_for_each_child_node() as it will automatically
increase and decrease the refcounter.
