ASoC: fsl: fsl_qmc_audio: Reset audio data pointers on TRIGGER_START event
On SNDRV_PCM_TRIGGER_START event, audio data pointers are not reset.
This leads to wrong data buffer usage when multiple TRIGGER_START are
received and ends to incorrect buffer usage between the user-space and
the driver. Indeed, the driver can read data that are not already set by
the user-space or the user-space and the driver are writing and reading
the same area.
Fix that resetting data pointers on each SNDRV_PCM_TRIGGER_START events.
