## What changes were proposed in this pull request?
[SPARK-5100](343d3bfafd) added Spark Thrift Server(STS) UI and the following logic to handle exceptions on case `Throwable`.
```scala
HiveThriftServer2.listener.onStatementError(
statementId, e.getMessage, SparkUtils.exceptionString(e))
```
However, there occurred a missed case after implementing [SPARK-6964](eb19d3f75c)'s `Support Cancellation in the Thrift Server` by adding case `HiveSQLException` before case `Throwable`.
```scala
case e: HiveSQLException =>
if (getStatus().getState() == OperationState.CANCELED) {
return
} else {
setState(OperationState.ERROR)
throw e
}
// Actually do need to catch Throwable as some failures don't inherit from Exception and
// HiveServer will silently swallow them.
case e: Throwable =>
val currentState = getStatus().getState()
logError(s"Error executing query, currentState $currentState, ", e)
setState(OperationState.ERROR)
HiveThriftServer2.listener.onStatementError(
statementId, e.getMessage, SparkUtils.exceptionString(e))
throw new HiveSQLException(e.toString)
```
Logically, we had better add `HiveThriftServer2.listener.onStatementError` on case `HiveSQLException`, too.
