hwmon: (emc2305) fix device node refcount leak in error path
The for_each_child_of_node() macro automatically manages device node
reference counts during normal iteration. However, when breaking out
of the loop early with return, the current iteration's node is not
automatically released, leading to a reference count leak.
Fix this by adding of_node_put(child) before returning from the loop
when emc2305_set_single_tz() fails.
This issue could lead to memory leaks over multiple probe cycles.
