However, this doesn't actually happen when the UEFI Shell 2.0 method is used (which is basically "always" nowadays). Accordingly, the only caller of ShellOpenFileByDevicePath(), namely ShellOpenFileByName(), defines a (dummy) local DeviceHandle variable just so it can call ShellOpenFileByDevicePath(). Remove the useless output parameter.
