ASoC: soc-pcm.c: tidyup playback/capture_only at soc_get_playback_capture()

soc_get_playback_capture() (A) returns number of substreams for
playback/capture, and then, we can use playback/capture_only flag (X)(Y).

(A)     static int soc_get_playback_capture(...)
	{
		...
(X)		if (dai_link->playback_only) {
(*)			*playback = 1;
			*capture = 0;
		}

(Y)		if (dai_link->capture_only) {
			*playback = 0;
(*)			*capture = 1;
		}
		...
	}

But this flag should not have effect to opposite side stream (*).
This patch tidyup it.
