* fix: treat chdev execution failures as module errors in aix_devices
##### SUMMARY
Fix the aix_devices module so that a failed chdev command is reported as a module failure instead of a successful result.
The previous implementation called fail_json incorrectly by returning success through the normal completion path when chdev returned a non-zero exit status. This could allow a playbook to continue even though the requested device attribute change was not applied.
This change replaces the success-style error handling with proper failure handling in the chdev execution path, making task results consistent with the actual command outcome.
##### ISSUE TYPE
- Bugfix Pull Request
##### COMPONENT NAME
aix_devices
##### ADDITIONAL INFORMATION
The affected code path is in change_device_attr() when the module executes chdev to apply attribute updates.
Before this change:
- chdev could fail
- the module could still report success
- later tasks could run against an unexpected system state
After this change:
- chdev failures are returned through fail_json
- the task stops with an error
- playbook behavior matches the real execution result
```paste below
Before:
module.exit_json(msg="Failed to run chdev.", rc=rc, err=err)
After:
module.fail_json(msg="Failed to run chdev.", rc=rc, err=err)
```
