ASoC: msm-cpe-lsm: Fix erroneous data channel close

For buffering after keyword detection, it is possible that buferring may
get stopped even before data channel setup is completed. This will
result into closing the channel that was not established at all. Fix
this issue by making sure data channel is always established after
keyword detection.
