ctdb-recoverd: Drop explicit check to flag takeover run needed

The recovery daemon should be less involved in the service monitoring
logic.

The cases handled here are already handled elsewhere:

* When a node becomes unhealthy/healthy the monitoring code will
  trigger a takeover run

* When a node is disabled/enabled the ctdb CLI tool will trigger a
  takeover run
