ASoC: sun4i-codec: return error code instead of NULL when create_card fails

When sun4i_codec_create_card fails, we do not assign a proper error
code to the return value. The return value would be 0 from the previous
function call, or we would have bailed out sooner. This would confuse
the driver core into thinking the device probe succeeded, when in fact
it didn't, leaving various devres based resources lingering.

Make the create_card function pass back a meaningful error code, and
assign it to the return value.
