[OSS-Tools] [PATCH dt-utils 2/5] state: helpful error message if state GUID cannot be found

["Enrico Jörns" <ejo@pengutronix.de>]

Port of barebox commit:

| state: helpful error message if state GUID cannot be found
|
| So far, if the user didn't specify a valid GPT UID, state initialization
| failed with the not so helpful error message:
|
| | ERROR: state state.of: probe failed: Invalid argument
|
| Improve this by also providing a helpful error message.
