[PATCH 6.19 238/844] ASoC: qcom: q6asm: drop DSP responses for closed data streams

[ Upstream commit 8a066a81ee0c1b6cdbd81393536c3b2d19ccef25 ]
'Commit a354f030dbce ("ASoC: qcom: q6asm: handle the responses
after closing")' attempted to ignore DSP responses arriving
after a stream had been closed.
However, those responses were still handled, causing lockups.
Fix this by unconditionally dropping all DSP responses associated with
closed data streams.
