app_confbridge: Fixed "CBAnn" channels not going away.

Fixed a ref leak in conf_handle_talker_cb() everytime the conference
bridge was found to report a channel's talker status change.  The
resulting leak caused the "CBAnn" channels and the conference bridge to
never be destroyed.

Thanks to Richard Kenner on the asterisk-user's list for locating the
problem.
