target/ppc: Fix warning with clang-15

When compiling for windows-arm64 using clang-15, it reports a sometimes
uninitialized variable. This seems to be a false positive, as a default
case guards switch expressions, preventing to return an uninitialized
value, but clang seems unhappy with assert(0) definition.

Change code to g_assert_not_reached() fix the warning.
