platform/x86: think-lmi: Fix issues with duplicate attributes
On an AMD based Lenovo T14, I find that the module doesn't work at all, and instead has a traceback with messages like: ``` sysfs: cannot create duplicate filename '/devices/virtual/firmware-attributes/thinklmi/attributes/Reserved' ``` Duplicate and reserved values showing up appear to be a firmware bug, but they shouldn't make the driver explode. So catch them and skip them.
