audio: copier: use v_index for DAI index in I2S link creation

This commit updates the copier DAI creation logic for I2S links to use
the `v_index` field from the `node_id` structure as the DAI index. This
change ensures that the correct DAI index is used when creating I2S links,
aligning with the new SSP link management mechanism.
