checkout,clone: check return value of create_symref
It's unlikely that we would fail to create or update a
symbolic ref (especially HEAD), but if we do, we should
notice and complain. Note that there's no need to give more
details in our error message; create_symref will already
have done so.
While we're here, let's also fix a minor memory leak in
clone.
