Subject: ASoC: dmaengine: Add config parameter NULL check.

ASoC: dmaengine: Add config parameter NULL check.

Because the "ASoC: dmaengine-pcm: Provide default config" has provided
us one defualt config of DMA. When using this, the config parameter of
devm_snd_dmaengine_pcm_register() will be NULL, so here we need to have
a check before using it.
