Subject: netfilter 06/29: netns ebtables: more cleanup during ebt_unregister_table()

commit dbcdf85a2e3d2aa584dafd10b5a1f42764e673e7

    netfilter: netns ebtables: more cleanup during ebt_unregister_table()
    
    Now that ebt_unregister_table() can be called during netns stop, and module
    pinning scheme can't prevent netns stop, do table cleanup by hand.
