Work around two -Werror=implicit-fallthrough=

...that started to crop up with recent GCC 12 trunk (where it expanded
the ENSURE_OR_THROW macro, but apparently didn't take into account that its

>    97 |     if( !(c) ){ \
>       |     ^~

will always be taken in these cases where the c argument is false), and
can easily be avoided by getting rid of those uses of
ENSURE_OR_THROW(false, "...")

(And while at it, move the default case to a more reasonable position in
mtftools.cxx, obsoleting the FALLTHROUGH comment in any case.)
