This patch fix the second dai driver's dai widget can't connect to the endpoint. Because "bt-sco-pcm" and "bt-sco-pcm-wb" dai driver have the same stream_name, so it will cause they have the same widget name. Therefor it will just create only one route when do snd_soc_dapm_add_route that only find the widget through the widget name.
