114e51fb9a sdm: Cancel display event thread on exit. 
- Send a cancellation request to display event thread before waiting
  for it join. This thread waits for poll to return indefinitely
  which may not return if all of the events (vsync etc) are in
  disabled state.
- Drop this call for Android for now as this api is not supported in
  bionic.
- Fix GetVSyncState return value.
- Fix pwrite return value in case of set on idle time out.
