audio_open_output_stream always tries to open 1st registered endpoint based on assumption that there is only one endpoint registered anyway (due to support for only one codec). With more endpoints available in future we need to be able to retrieve endpoint id which is connected and use it for streaming. This patch adds special case for id=0 in open_stream IPC to return 1st opened endpoint on BlueZ side which is enough for now since only one headset can be connected at any time (i.e. we should not have more than 1 endpoint opened).
