[PATCH] ASoC: soc-card: remove card check

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

only snd_soc_card_set_bias_level() and snd_soc_card_set_bias_level_post()
are checking "card" in the function, like below

	int snd_soc_card_set_bias_level(...)
	{
		...
=>		if (card && card->xxx)
			ret = card->xxxx(...);
		...
	}

But it should already have been an error if "card" was NULL.
remove "card" NULL check here. Otherwise it will get waring on
smatch without this patch.
