ctdb-recoverd: Clear IP assignment tree on election loss
If a node was previously recovery master (say, 20 years ago) and it
becomes recovery master again then, if IP assignments have changed,
verify_remote_ip_allocation() can produce messages like the following
when called during recovery:
ctdbd: recoverd:Inconsistent IP allocation - node 0 thinks 10.1.1.1 is held by node 0 while it is assigned to node 1
When a node loses an election it should clear all data specific to it
being the recovery master.
