fix #1339: remove more locks from services IF the node got fenced

Remove further locks from a service after it was recovered from a
fenced node. This can be done due to the fact that the node was
fenced and thus the operation it was locked for was interrupted
anyway. We note in the syslog that we removed a lock.

Mostly we disallow the 'create' lock, as here is the only case where
we know that the service was not yet in a runnable state before.
