ASoC: core: Use kasprintf instead of opencoding it
kasprintf calculates the size of the result string, allocates a buffer large
enough to hold the string and then performs the format string operation. There
are a couple of places in ASoC where these three steps are done by hand and
where kasprintf can be used instead.
