    netfilter: Fix fall-through warnings for Clang
    
    [ Upstream commit c2168e6bd7ec50cedb69b3be1ba6146e28893c69 ]
    
    In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
    warnings by explicitly adding multiple break statements instead of just
    letting the code fall through to the next case.
