Unreachable code in an error handling block is listed in issue
https://gitlab.com/qemu-project/qemu/-/issues/2030.

After removing this code, the `fail` label is now immediately followed
by a test whose condition can never be true when coming explicitly
via this label. Moving the label down preserves the fall-through
case while avoiding testing an always false condition.

  tcg: Jump after always false condition
