    adb: fix buffer overflow while processing message payload
    
    Fix a heap buffer overflow (write) when the message header length is
    smaller than the actual message payload length. Add expert info to
    detect this since it can also occur when the header is wrongly matched
    with a data fragment (this dissector issue is not fixed here).
