Laurent Vivier 6ae6a30ca5 tests/qtest: failover: fix infinite loop 
If the migration is over before we cancel it, we are
waiting in a loop a state that never comes because the state
is already "completed".

To avoid an infinite loop, skip the test if the migration
is "completed" before we were able to cancel it.
