soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register
Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node. When breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node. Add missing of_node_put() to avoid refcount leak.
