smart_amp_test: fix unbind implementation

[kv2019i]

Code in unbind is looking at wrong field for queue-id. This works some of the time, but in some cases leads to access to freed heap data and later to heap corruption.

Link: #7191

[kv2019i]

@ranj063 @andrula-song @RanderWang This fixes a clear error that leads to heap corruption with our nocodec topologies. I noticed we still have #7101 open (to remove unbind-bind), but that has not moved forward.

@kv2019i im going to close 7101 in favor of @andrula-song 's PR to modify the smartamp to use module adapter

[RanderWang]

Thanks! I also fixed in my PR #7259. But I forgot to submit it when closing my PR
