Subject: ASoC: compress: Derive substream from stream based on direction

From: Satish Babu Patakokila <sbpata@codeaurora.org>

commit 01b8cedfd0422326caae308641dcadaa85e0ca72 upstream.

Currently compress driver hardcodes direction as playback to get
substream from the stream. This results in getting the incorrect
substream for compressed capture usecase.
To fix this, remove the hardcoding and derive substream based on
the stream direction.
