ASoC: Fail card instantiation if DAI format setup fails

BugLink: https://bugs.launchpad.net/bugs/1842114
[ Upstream commit 40aa5383e393d72f6aa3943a4e7b1aae25a1e43b ]

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.
