cli: Fix double check of remote workspace version

After verifying the remote backend workspace version is compatible with
the local Terraform version, we need to record that this check was
successful. Otherwise the fallback error handling path will run a strict
version check, even if the versions are compatible, which will cause an
unexpected failure.
