ASoC: Fix SND_SOC_DAPM_LINE handling
Since the SND_SOC_DAPM_LINE can be input or output, additional check is needed in order to determine if the widget is connected as input or output. When checking for connected outputs, if the widget is line, than check if the sources list is not empty (line is connected as output) For input endpoint check, when the widget is line, also check if the sinks list is not empty (line is connected as input).
