From: Pierrick Bouvier <pierrick.bouvier@linaro.org>

Use of assert(false) can trip spurious control flow warnings from
some versions of GCC (i.e. using -fsanitize=thread with gcc-12):

  error: control reaches end of non-void function [-Werror=return-type]
        default:
            assert(0);
      | }
      | ^

Solve that by unifying the code base on g_assert_not_reached() instead.
