Assuming the calibration state gets lost after system suspend. Resets cali_done when suspending.

The rt1015_priv is alloced by kzalloc. No need to initialize cali_done to 0 in component probe callback.

The device could lose the calibration state after suspend/resume. It is better to reset the flag and get chance to calibrate again.

The patch applies after the series: https://mailman.alsa-project.org/pipermail/alsa-devel/2020-December/178608.h...
