Win32: fixed wrong type cast.
GetQueuedCompletionStatus() document on MSDN says the
following signature:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa364986.aspx
BOOL WINAPI GetQueuedCompletionStatus(
_In_ HANDLE CompletionPort,
_Out_ LPDWORD lpNumberOfBytes,
_Out_ PULONG_PTR lpCompletionKey,
_Out_ LPOVERLAPPED *lpOverlapped,
_In_ DWORD dwMilliseconds
);
In the latest specification, the type of the third argument
(lpCompletionKey) is PULONG_PTR not LPDWORD.
