ASoC: bt-sco: fix bt-sco-pcm-wb dai widget don't connect to the endpoint

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.
