Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put under the label that the gotos point to. In order to avoid decrementing an already-decremented refcount, copy the original contents of the label (including the return statement) to just above the label, so that the code under the label is executed only when a goto exit from the loop occurs. Additionally, remove an unnecessary get/put pair from the loop, as the loop itself already keeps track of refcount. Issue found with Coccinelle.
