Fix typo in IAsyncOperation<int> GUID

Fixing a typo in the IAsyncOperation<int> GUID declaration to match the
original value it purports to be a copy of. Without this change if this
declaration is ever included in the same context as a declaration using
the correct GUID from the SDK, the conflicting values will cause
failures in several of the related COM calls around QueryInterface.
