tbm_surface_queue: Added some enum value for checking detail errors.

 TBM_SURFACE_QUEUE_ERROR_ALREADY_EXIST -6
  - It will be returned from tbm_surface_queue_enqueue when tbm_surface is not sequential.
 TBM_SURFACE_QUEUE_ERROR_UNKNOWN_SURFACE -7
  - It will be returned from tbm_surface_queue_enqueue when tbm_surface is not exist in free or dirty queue.
