ACPI: thinkpad-acpi: don't misdetect in get_thinkpad_model_data() on -ENOMEM
Explicitly check for memory allocation failures, and return status to
indicate that we could not collect data due to errors.
This lets the driver have a far more predictable failure mode on ENOMEM in
that codepath: it will refuse to load. This is far better than trying to
proceed with missing data which is used to detect quirks, etc.
