[PATCH] hw/audio/sb16: Do not migrate qdev properties

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since commit f7b4f61f63 ("qdev/isa: convert soundblaster") these
fields has been converted to qdev properties, so don't need to be
migrated:

  static Property sb16_properties[] = {
      DEFINE_AUDIO_PROPERTIES(SB16State, card),
      DEFINE_PROP_UINT32 ("version", SB16State, ver,  0x0405), /* 4.5 */
      DEFINE_PROP_UINT32 ("iobase",  SB16State, port, 0x220),
      DEFINE_PROP_UINT32 ("irq",     SB16State, irq,  5),
      DEFINE_PROP_UINT32 ("dma",     SB16State, dma,  1),
      DEFINE_PROP_UINT32 ("dma16",   SB16State, hdma, 5),
      DEFINE_PROP_END_OF_LIST (),
  };
