ASoC: soc-core.c: Prefer to return dai->driver->name in snd_soc_dai_name_get()

ASoC machine driver can use snd_soc_{of_}get_dlc() (A) to get DAI name
for dlc (snd_soc_dai_link_component). In this function call
dlc->dai_name is parsed via snd_soc_dai_name_get() (B).

(A)	int snd_soc_get_dlc(...)
	{
		...
(B)		dlc->dai_name = snd_soc_dai_name_get(dai);
		...
	}

(B) has a priority to return dai->name as dlc->dai_name. In most cases
card can probe successfully. However it has an issue that ASoC tries to
rebind card. Here is a simplified flow for example:

 |	a) Card probes successfully at first
 |	b) One of the component bound to this card is removed for some
 |	   reason the component->dev is released
 |	c) That component is re-registered
 v	d) ASoC calls snd_soc_try_rebind_card()

a) points dlc->dai_name to dai->name. b) releases all resource of the
old DAI. c) creates new DAI structure. In result d) can not use
dlc->dai_name to add new created DAI.

So it's reasonable that prefer to return dai->driver->name in
snd_soc_dai_name_get() because dai->driver is a pre-defined global
variable. Also update snd_soc_is_matching_dai() for alignment.
