[PATCH] ASoC: soc-generic-dmaengine-pcm: Fix error handling

[Shengjiu Wang]

Remove the return value checking, that is to align with the code
before adding snd_dmaengine_pcm_refine_runtime_hwparams function.

Otherwise it causes a regression on the HiKey board:

[   17.721424] hi6210_i2s f7118000.i2s: ASoC: can't open component f7118000.i2s: -6

   ASoC: soc-generic-dmaengine-pcm: Fix error handling

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
