thermal: of: fix OF node leak in of_thermal_zone_find()
of_thermal_zone_find() calls of_parse_phandle_with_args(), but does not
release the OF node reference obtained by it.
Add a of_node_put() call when the call is successful.
Fixes: 3fd6d6e2b4e8 ("thermal/of: Rework the thermal device tree initialization")
