In some parts of the mtce code some implicit fallthrough are used.
This causes a warning in the compiler and in OSes like openSUSE the
-Werror flag is enforced leading to a build error.
In this commit the __attribute__ ((fallthrough)) is used to tell the
compiler to not worry about this implicit fallthroughs as the it works
as intended.
