ASoC: Avoid putting stream state to STOP when stream paused
ASoC: Avoid putting stream state to STOP when stream paused

When multiple Front-end are using the same Back-end, putting
the stream state for a Front-end to STOP will make the the Backend
stream to be released, when the front-end is paused. This will avoid
the Backend to be released (when another active front-end stream is
present).
Instead, put the stream state to PAUSED, which will keep the Back-end
ON.
