ASoC: sof: Improve sof_ipc3_bytes_ext_put function
The function is improved in the way that if the firmware returns a validation error on the newly sent bytes, then the kernel will automatically restore to the old bytes value for a given kcontrol. This way, if the firmware rejects a data blob then the kernel will also reject it, instead of saving it for the next suspend/resume cycle. The old behaviour is that the kernel would save it anyway and on next firmware boot it would apply the previously-rejected configuration, leading to errors during playback. Additionally, the function also saves previously validated configurations, so that if the firmware does end up rejecting a new bytes value the kernel can send an old, previously-valid configuration.
