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.

applied by Mark:

Thanks for pointing this, Yes, It is fixed in sound-next.. my branch was 
a week+ old so did not spot it :-)
