recoverd: All inactive nodes should yield recovery master role

recoverd: All inactive nodes should yield recovery master role

Not just stopped nodes.  In reality, this means that banned nodes will
also yield, since nodes in the other inactive states won't be running
a daemon.

This seems sensible since if another node notices that an inactive
node is the recovery master then it will force an election anyway.
