ASoC: Intel: avs: Disconnect substream if suspend or resume fails

Browse Source 
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.
