ole32: Reread the stream entry after setting the size in StreamWriteAt.

In simple mode, StreamWriteAt would assume that StreamSetSize uses the size
it asks for, but in some cases the size would be pushed above the small block
limit. StreamWriteAt would then attempt to write using a small block chain,
even though a big block chain was created.
