panic in WaitForBootstrapComplete

When running an overnight run in dev-scripts (COMPACT_IPV4) with repeated installs I saw this panic in WaitForBootstrapComplete occur once.

4.12.0-0.nightly-2022-10-25-210451

Occurred on the 12th run, all previous installs were successfule

1.Set up dev-scripts for  AGENT_E2E_TEST_SCENARIO=COMPACT_IPV4, no mirroring
2. Run 'make clean; make agent' in a loop
3. After repeated installs got the failure

Panic in WaitForBootstrapComplete

No failure

It looks like clusterResult is used here even on failure, which causes the dereference - https://github.com/openshift/installer/blob/master/pkg/agent/rest.go#L121
