ASoC: qcom: q6asm-dai: perform correct state check before closing

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.
