Subject: [PATCH] ASoC: soc-compress: set pcm nonatomic flag from dai_link

In compress offload case we never set nonatomic flag on a new pcm. This triggers
below configuration error with DPCM on Qualcomm setup where dai_links are marked
as nonatomic.

"FE is atomic but BE is nonatomic, invalid configuration"

Fix this by Updating the pcm nonatomic flag correcly from the respective dai_link.
