Subject: [PATCH 2/5] ASoC: Fix incorrect kfree in ad193x_probe error path

We allocated memory for ad193x in ad193x_spi_probe,
and will free the memory in either ad193x_spi_probe error path or
ad193x_spi_remove.

Thus we should not call kfree(ad193x) in ad193x_probe, otherwise
we have double free of ad193x.
