Converted bang to ask to avoid scary warning when a block is removed
Removing a block through the blockmanager gave a scary warning messages in
the driver.
```
2014-05-08 20:16:19,172 WARN BlockManagerMasterActor: Got unknown message:
true
2014-05-08 20:16:19,172 WARN BlockManagerMasterActor: Got unknown message:
true
2014-05-08 20:16:19,172 WARN BlockManagerMasterActor: Got unknown message:
true
```
This is because the
[BlockManagerSlaveActor](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/storage/BlockManagerSlaveActor.scala#L44)
would send back an acknowledgement ("true"). But the BlockManagerMasterActor
would have sent the RemoveBlock message as a send, not as ask(), so would
reject the receiver "true" as a unknown message.
