Subject: [PATCH net] net: ehea: fix possible memory leak in ehea_register_port()

dev_set_name() in ehea_register_port() allocates memory for name,
it need be freed when of_device_register() fails, call put_device()
to give up the reference that hold in device_initialize(), so that
it can be freed in kobject_cleanup() when the refcount hit to 0.
