net: hns: fix possible memory leak in hnaeaeregister()

Inject fault while probing module, if deviceregister() fails, but the refcount of kobject is not decreased to 0, the name allocated in devsetname() is leaked. Fix this by calling putdevice(), so that name can be freed in callback function kobjectcleanup().
