Subject: [PATCH 3/5] ASoC: Fix incorrect kfree in aic3x_probe error path

We allocated memory for aic3x in aic3x_i2c_probe,
and will free the memory in either aic3x_i2c_probe error path or
aic3x_i2c_remove.

Thus we should not call kfree(aic3x) in aic3x_probe, otherwise
we have double free of aic3x.
