[PATCH 2/2] ASoC: core: fix the memory leak in case of remove_aux_dev()

[Chuansheng Liu]

When probing aux_dev, initializing is as below:
device_initialize()
device_add()

So when remove aux_dev, we need do as below:
device_del()
device_put()
Otherwise, the rtd_release() will not be called.

So here using device_unregister() to replace device_del(),
like the action in soc_remove_link_dais().
