ASoC:intel:skl:fix a simultaneous playback & capture issue on hda platform
[ Upstream commit c899df3e9b0bf7b76e642aed1a214582ea7012d5 ]
If playback and capture are enabled concurrently, when the capture stops
the output becomes inaudile. The playback application will become stuck
and underrun after a timeout.
This is caused by mistaken use of the stream_id, which should only be
set for playback and not for capture
Tested on Apollolake and Kabylake with SST driver.
