thermal: of: fix OF node leak in of_thermal_zone_find()

Browse Source 
[ Upstream commit 9164e0912af206a72ddac4915f7784e470a04ace ]

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.
