ASoC: msm: qdsp6v2: allow zero size calibration for LSM

Browse Source 
It is possible that LSM (Listen Stream Manager) could have an usecase
that does not need any audio calibration. In such cases, currently
the driver returns an error and does not allow the usecase setup with
LSM causing the usecase to fail. Fix this by allowing zero size audio
calibration for LSM.
