    reassemble: remove special treatment for truncated data
    
    Do not try to recover from truncated tvbs for fragment_add_seq-like
    functions:
    
     - If it is the first block and the dissector requested frag_data_len
       number of bytes, we should not lie and pretend that we are fully
       reassembled.
     - For other blocks, returning NULL as no reassembly was possible makes
       sense. But other fragments in the list should not be cleared as there
       may be partial fragments which were returned before.
    
    It seems that this special behavior was introduced in
    b2c11b5e13248b1c98ee5104eab411e842911e19 (freeing fragments and
    returning NULL as an optimization when fragments are deemed not needed
    anymore) and faeb2c2ee16e61e54c880163e98d6528dd0c5619 (for returning
    fd_head for the first fragment, "so the first fragment gets dissected as
    fragmented packet").
    
    Now in theory unused fragments could stick around, but that also
    possible with the normal fragment_add functions.
