counter: stm32-timer-cnt: fix device_node handling in probe_encoder()
commit 147359e23e5c9652ff8c5a98a51a7323bd51c94a upstream.
Device nodes accessed via of_get_compatible_child() require
of_node_put() to be called when the node is no longer required to avoid
leaving a reference to the node behind, leaking the resource.
In this case, the usage of 'tnode' is straightforward and there are no
error paths, allowing for a single of_node_put() when 'tnode' is no
longer required.
