Windows: WinUSB: Do not assume that driver implements CancelIoEx()
Cancelling an individual OVERLAPPED I/O operation is something that a
driver can optionally implement. It appears that the native WinUSB
driver supports this but libusbK does not. Therefore we will attempt
to use it and fall back to the AbortPipe() call if an error occurs.
Closes #400
