Commit cce6c149eba3a ("ASoC: Intel: Skylake: add link management") added a perfectly logical/symmetrical link handling for 'suspend_active' aka S0ix
However that commit also added a less obvious part, where during S3 resume the code will "turn off the links which are off before suspend" as well as stop the cmd_io which is not started.
This sequence looks completely unnecessary and possibly wrong, remove it.
