This fix a bug in dapm_widget_power_read_file(), where it may sent opposite order of source/sink widget into the p->connected().

for example, static int connected_check(source, sink); {"w_sink", NULL, "w_source", connected_check}

the dapm_widget_power_read_file() will query p->connected() in following case p->conneted("w_source", "w_sink") p->conneted("w_sink", "w_source") we should avoid the last case, since it's the wrong order (source/sink) as declared in snd_soc_dapm_route.
