nvmem: core: fix error handling while validating keepout regions
Current error path on failure of validating keepout regions is calling
put_device, eventhough the device is not even registered at that point.
Fix this by adding proper error handling of freeing ida and nvmem.
Fixes: fd3bb8f54a88 ("nvmem: core: Add support for keepout regions")
