Remove unnecessary error log from CurrentFabricRemover

Currently, when the CurrentFabricRemover is successful it logs the
following error with err log level:

Remove Current Fabric Result : src/controller/CurrentFabricRemover.cpp:133: Success

Get rid of the message if successful, it is confusing.

src/controller/CurrentFabricRemover.cpp
