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.
