[PATCH v2] drivers/thermal/tegra: Fix a double free on the device node

[zhong jiang]

The function 'for_each_child_of_node' iterates over the node list by
dropping the of_node reference of the previous node.

Calling of_node_put() on the iterator is pointless and leads to an
inconsistent refcounting in addition to a double free. Remove it.

v1->v2: According to Daniel's suggestion. I modify the subject and commit log.
