ASoC: msm: qdsp6v2: Add mutex in afe_map_cal_data

Add mutex_lock in afe_map_cal_data around afe_cmd_memory_map to
avoid update of this_afe.status by afe_set_lpass_clk_cfg afe callback.
This fixes the failure of afe_cmd_memory_map waitqueue to enter into
sleep when wait_event_timeout is called as this_afe.status is already
zero leading to invalid map_handle.
