ASoC: soc-dapm.c: remove no meaning variable from snd_soc_dapm_add_path()

snd_soc_dapm_add_path() is using local variable "widgets[]", but it is
same as path->node[].
This is no meaning and duplicate operation. This patch removes "widgets[]".

	path->node[SND_SOC_DAPM_DIR_IN] = wsource;
	path->node[SND_SOC_DAPM_DIR_OUT] = wsink;
	widgets[SND_SOC_DAPM_DIR_IN] = wsource;
	widgets[SND_SOC_DAPM_DIR_OUT] = wsink;
