ctdb-recoverd: Freeze databases whenever the node is INACTIVE

ctdb-recoverd: Freeze databases whenever the node is INACTIVE

active, then it will never freeze the databases, and hence the
node will keep banning itself indefinitely, until ctdbd is restarted.

This is a regression from 4.3, introduced with

b4357a79d916b1f8ade8fa78563fbef0ce670aa9

and
