    ASoC: rsnd: tidyup direction name on rsnd_dai_connect()

    commit 2c6b6a3 ("ASoC: rsnd: use snd_pcm_direction_name()") uses
    snd_pcm_direction_name() instead of original method to get string
    "Playback" or "Capture". But io->substream might be NULL in this timing.
    Let's re-use original method.
