Yes that's the case, I verified that already. While the freeze state
actively unfreezes services if a nodes LRM comes back online again the
error state doesn't.
The error state has only one wait out and that's disabling the service
(and naturally removing it from HA works also, but that works for every
state always).
I'll prepare a patch.
