ASoC: dapm: fix debugfs read using path->connected
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.
