The ShellOpenFileByDevicePath() API promises to set the DeviceHandle output parameter to the handle of the filesystem identified by the FilePath input parameter. 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.
