[SPARK-19398] remove one misleading log in TaskSetManager.
## What changes were proposed in this pull request?
Log below is misleading:
```
if (successful(index)) {
logInfo(
s"Task ${info.id} in stage ${taskSet.id} (TID $tid) failed, " +
"but another instance of the task has already succeeded, " +
"so not re-queuing the task to be re-executed.")
}
```
If fetch failed, the task is marked as successful in TaskSetManager::
handleFailedTask. Then log above will be printed. The successful just means
task will not be scheduled any longer, not a real success.
## How was this patch tested?
Existing unit tests can cover this.
