    net: Remove unnecessary net action assertion
    
    The extra assertion to allow packet munging only when there are
    no other ptypes listening which may have worked around an old bug
    is unnecessary. It is sufficient to check if the skb is cloned before
    trampling on it. Thanks to Herbert Xu for being persistent and patient
    in getting this across.
    [Note that cloning checks and assertions are the general rule used
    by tc actions (documentation/networking/tc-actions-env-rules.txt)].
