If the DAI format setup fails, there is no valid communication format between CPU and CODEC, so fail card instantiation, rather than continue with a card that will most likely not function properly.

This is another one where if nobody noticed a problem already and things just happened to be working this might break things, it's vanishingly unlikely to fix anything that was broken.
