unreachable() doesn't lead to executing the code that follows it,
neither in debug nor release builds. So falling through doesn't make any
sense.
This fixes a compile-error on clang.
Let's move the default-block to the end to make it clearer that there's
no intended fallthrough.

Because of incomplete codepaths further down in this function, we end up
trying to use this variable without initialization. Let's initialize it
to zero, just to keep the compiler happy.
This avoids a compile-time warning, which would get treated as an error
on CI.
