Wrong argument used in StreamTask when user-defined backend is used

[Vladislav Pernin]

https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L716

This should be :

LOG.info("Using user-defined state backend: {}.", fromJob);
