[patch] ASoC: fsl: add an error check

[Dan Carpenter]

My static checker complains that:

	sound/soc/fsl/imx-wm8962.c:196 imx_wm8962_probe() warn:
	we tested 'ret' before and it was 'false'

The intent was that we use "ret" to check imx_audmux_v2_configure_port().

Fixes: 8de2ae2a7f1f ('ASoC: fsl: add imx-wm8962 machine driver')

I assume checking for an error here will not change anything but I have
not tested this patch.
