Fix a memory leak in ResourceDispatcher

When we delete a ResourceLoaderBridge before OnCompletedRequest is received, bad things happen. There's a lot of leaks at the following points:
1. OnMessageReceived ignores the message.
2. RemovePendingRequest removes it's internal deferred_message_queue.

But ViewHostMsg_Resource_DataReceived is not POD. We should also close the shared memory handle inside it.
