    hsr: implement dellink to clean up resources · b9a1e627

    hsr_link_ops implements ->newlink() but not ->dellink(),
    which leads that resources not released after removing the device,
    particularly the entries in self_node_db and node_db.
    
    So add ->dellink() implementation to replace the priv_destructor.
    This also makes the code slightly easier to understand.
