thinkpad-acpi: acpi_evalf fixes
Use acpi_format_exception() in acpi_evalf() instead of logging numeric
errors.
Also, when ACPICA returns an error, we should not be touching the return
object, as it is invalid. In debug mode, acpi_evalf() callers would
printk the returned crap (but fortunately, not use it).
