ASoC: soc-core: Pre-check zero CPU/codec DAIs, handle early rtd->dais alloc failure

Browse Source 
This commit adds a pre-check in ASoC to ensure there are non-zero CPU or
codec DAIs. It also handles early failure of memory allocation for
rtd->dais by going to the cleanup path, preventing potential issues
from invalid configurations or out-of-memory situations.
