gianfar: ethtool: Fix refcount leak in gfar_get_ts_info
[ Upstream commit 2ac5b58e645c66932438bb021cb5b52097ce70b0 ]
The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.
