ASoC: msm-cpe-lsm: Queue 2 buffers with slimbus before afe start

When userspace requests small duration of buffer then it is possible
that the buffer can overflow if only one buffer is queued at a time.
This is because of more channel setup time than buffer size duration.
Queue two buffers with slimbus before starting AFE port to avoid
data loss.
