of: do not use "%pOF" printk format on node with refcount of zero

of_node_release() can not use the "%pOF" printk format to report
the node name of a node when the node reference count is zero.
This is because the formatter device_node_string() calls
fwnode_full_name_string() which indirectly calls of_node_get().
Calling of_node_get() on the node with a zero reference count
results in a WARNING and stack trace.

When the reference count has been decremented to zero, this function
is in the subsequent call path which frees memory related to the node.

This commit resolves the unittest EXPECT errors that were created in
the previous commmit.
