ASoC: msm-cpe: Fix sequence for data channel teardown

The data channel for buffering has two endpoints, one on the MSM and
another on the codec. When codec endpoint is torn down, it waits for an
interrupt for channel teardown from hardware. But, since MSM endpoint is
still connected, the interrupt is never receieved and the codec wait
gets timed out. This adds delay in data channel teardown. Fix this issue
by making sure the MSM endpoint is torn down first and then the codec
endpoint gets torn down.
