Update on what happens after TOI failure.

After TOI error that node will not serve user anymore, you either get
ERROR 40001: WSREP replication failed. Check your wsrep connection state
and retry the query.
ERROR 08S01: WSREP has not yet prepared node for application use
User KILL will return the first one. bf_kill can't happen as you can't
issue commands to cause it.
