* gnu/services/pm.scm (tlp-shepherd-service): Make destructor
return #f on success. Destructor "should return #f if it is
now possible again to start the service at a later point"
(shepherd manual).

Without this patch tlp service brings annoying messages "Service tlp might
have failed to stop" to the system log. Thanks to lfam and Rutherther on
IRC for mentioning in relation to other service that the destructor of a
shepherd service should return #f on success.
