ASoC: soc-pcm: fixup dpcm_prune_paths() loop continue

Browse Source 
dpcm_prune_paths() is checking widget at 2 parts.
(A) is for CPU, (B) is for Codec.
If we focus to (A) part, continue at (a) is for (1) loop. But,
if we focus to (B) part, continue at (b) is for (2) loop, not for (1).
This is bug.
This patch fixup this issue.

	static int dpcm_prune_paths(...)
	{
		...
   (1)		for_each_dpcm_be(fe, stream, dpcm) {
			...

 ^			widget = dai_get_widget(...);
 |
(A)			if (widget && widget_in_list(...))
 | (a)				continue;
 v
 ^ (2)			for_each_rtd_codec_dai(...) {
 |				widget = dai_get_widget(...);
(B)
 |				if (widget && widget_in_list(...))
 v (b)					continue;
			}
			...
