[PATCH v2] ASoC: soc-card: remove card check

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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. This is prepare for error check cleanup.
