sensord: fix double-free issue

- If the server is terminated unexpectedly, sensor library releases the memory
  of channel automatically. At that time, if client calls disconnect(),
  double-free problem is invoked.
- Because it is right situation to call disconnect() explicitly,
  the auto-release code should be removed.
