To improve performance and overall system stability, suspend/resume operations for ASoC cards always return success status and defer the actual work.
Because of that, if a substream fails to resume, userspace may still attempt to invoke commands on it as from their perspective the operation completed successfully. Set substream's state to DISCONNECTED to ensure no further commands are attempted.

Hm, that might work, but note that, once when the stream is set with the disconnected state, it won't be taken back to the normal state any longer on most sound backends. That is, it'll be gone and won't revive unless you completely unload and reload the whole stuff. If that's the intended behavior, that's fine, of course. So just to make sure.
