Print usage in md380-tool if parameters used wrong #872

md380-tool succeeds silently if called with an invalid command (eg. md380-tool flaashdump foo.bin) or a valid command missing arguments (md380-tool flashdump). Print usage then to inform the user that nothing happened and they should call it properly.
