gadget: f_thor: annotate switch/case fallthrough

Even though we seem to catch POWEROFF and EFSCLEAR commands in the THOR
protocol request handling, we ultimately do not seem to handle them
(apart from sending a response), so those commands still print an error
message.

Annotate the switch/case fallthrough in this case, to make this clear to
the compiler.
