commit bfbb12dfa144d45575bcfe139a71360b3ce80237 upstream.
Do not stop a q6asm stream if its not started, this can result in unnecessary dsp command which will timeout anyway something like below:
q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: CMD 10bcd timeout
Fix this by correctly checking the state.
