ASoC: soc-dapm: set bias_level if snd_soc_dapm_set_bias_level() was successed

[ Upstream commit f40ecc2743652c0b0f19935f81baf57c601eb7f0 ]

ASoC has 2 functions to set bias level.
	(A) snd_soc_dapm_force_bias_level()
	(B) snd_soc_dapm_set_bias_level()

snd_soc_dapm_force_bias_level() (A) will set dapm->bias_level (a) if
successed.

(A)	int snd_soc_dapm_force_bias_level(...)
	{
		...
		if (ret == 0)
(a)			dapm->bias_level = level;
		...
	}

snd_soc_dapm_set_bias_level() (B) is also a function that sets bias_level.
It will call snd_soc_dapm_force_bias_level() (A) inside, but doesn't
set dapm->bias_level by itself. One note is that (A) might not be called.

(B)	static int snd_soc_dapm_set_bias_level(...)
	{
		...
		ret = snd_soc_card_set_bias_level(...);
		...
		if (dapm != &card->dapm)
(A)			ret = snd_soc_dapm_force_bias_level(...);
		...
		ret = snd_soc_card_set_bias_level_post(...);
		...
	}

dapm->bias_level will be set if (A) was called, but might not be set
if (B) was called, even though it calles set_bias_level() function.

We should set dapm->bias_level if we calls
snd_soc_dapm_set_bias_level() (B), too.
