lib/nfs/Connection: fix crash while canceling a failing Open()
The method NfsConnection::CancellableCallback::Callback() will always invoke NfsConnection::Close() on the file handle, even if the void pointer is not a nfsfh. This can happen if the Open() was not successful, e.g. when the file does not exist.
