platform/x86: thinkpad_acpi: Only update profile if successfully converted

Randomly a Lenovo Z13 will trigger a kernel warning traceback from this
condition:

```
if (WARN_ON((profile < 0) || (profile >= ARRAY_SIZE(profile_names))))
```

This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.

Catch this situation and avoid updating the profile. Also log this into
dynamic debugging in case any other modes should be added in the future.
