Subject: [PATCH 4/8] ASoC: qcom: audioreach: fix ADSP ready check

currently q6apm_is_adsp_ready() will only return the cached value of
previous result. If we are unlucky and previous result is not-ready
then the caller will always get not-ready flag.

This is not correct, we should query the dsp of its current state in
irrespective of previous reported state.

Fixes: 47bc8cf60e92 ("ASoC: qdsp6: audioreach: Add ADSP ready check")
