Commit 957ce0c6b8a1 ("ASoC: soc-pcm: check symmetry after hw_params") moved the check for symmetry after we have set the cpu_dai's rate, channels and sample width to those in the params.

The symmetry check verifies that the cpu dai's stored parameters are the same as those in the params. Since we have only just stored these parameters, this makes the symmetry checks always pass.

Fix this by moving the symmetry check before we store the parameters, but after the parameters have been fixed up.
