ASoC: SOF: ipc4-topology: Only handle dai_config with HW_PARAMS for ChainDMA
The DMA Link ID is only valid in snd_sof_dai_config_data when the
dai_config is called with HW_PARAMS.
The commit that this patch fixes is actually moved a code section without
changing it, the same bug exists in the original code, needing different
patch to kernel prior to 6.9 kernels.
