software node: Fix device_add_software_node()
The function device_add_software_node() was meant to register the node supplied to it, but only if that node wasn't already registered. Right now the function attempts to always register the node. That will cause a failure with nodes that are already registered. Fixing that by incrementing the reference count of the nodes that have already been registered, and only registering the new nodes. Also, clarifying the behaviour in the function documentation.
