pkg/start: Do not .Run() when we fail to initialize from payload

leaderelection.RunOrDie.  Before that pivot, failing the load would
quickly shut down the process.  Since that pivot, until this commit,
failures such as [1]:

would cause InitializeFromPayload to error out before setting up
configSync with NewSyncWorkerWithPreconditions, but still call

to invoke runThrottledStatusNotifier.

With this commit, I'm returning to failing fast, and no longer calling
Operator.Run or later when we have trouble loading the payload.
