[SPARK-11334] numRunningTasks can't be less than 0, or it will affect
executor allocation
With Dynamic Allocation function, a task failed over ```maxFailure``` time,
all the dependent jobs, stages, tasks will be killed or aborted. In this
process, ```SparkListenerTaskEnd``` event will be behind in
```SparkListenerStageCompleted``` and ```SparkListenerJobEnd```. Like the Event
Log below:
```
{"Event":"SparkListenerStageCompleted","Stage Info":
Unknown macro: {"Stage ID"}
Unknown macro: {"Event"}
{"Event":"SparkListenerTaskEnd","Stage ID":20,"Stage Attempt ID":0,"Task
Type":"ResultTask","Task End Reason":
Unknown macro: {"Reason"}
,"Task Info":{"Task ID":1955,"Index":88,"Attempt":2,"Launch
Time":1444914699763,"Executor
ID":"5","Host":"linux-223","Locality":"PROCESS_LOCAL","Speculative":false,"Getting
Result Time":0,"Finish Time":1444914699864,"Failed":true,"Accumulables":[]}}
```
Because that, the ```numRunningTasks``` in ```ExecutorAllocationManager```
class will be less than 0, and it will affect executor allocation.
