ASoC: dapm: Add missing return value check for snd_soc_dapm_new_dai
snd_soc_dapm_new_dai may return an error pointer and currently this
isn't checked for in dapm_connect_dai_link_widgets. Add code to check
the return value and not add routes in that case.
Fixes: 778ff5bb8689 ("ASoC: dapm: Move connection of CODEC to CODEC DAIs")
