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.

Fixes: 05589b30b2 ("soc: qcom: Extend AOSS QMP driver to support resources that are used to wake up the SoC.")
