splitmuxsink: fix sink pad release while PLAYING

Browse source 
- Release the split mux lock while removing the probes

- Flush the sinkpad to unblock other pads

- Turn check_completed_gop into a do while statement, when
  waking up we want to recheck whether the current GOP is
  ready for sending
