audio: fix race condition in EOF code

Don't return an EOF code if there's still buffered data.

Also, don't call demux_stream_eof() in the playloop. There's probably
nothing wrong with it, but it's cleaner not to use it.

Also give AD_EOF its own value, so that a decoding error doesn't drain
audio by causing an EOF condition.
