google/panther: Be safe about invalid thermal readings

In case we get an invalid thermal reading, let's run the fan
at full speed rather than at low speed. This might impact the
user experiance slightly in cases where the bad reading does
not happen while the system is hot, but it will increase stability
in the cases where the system is actually overheating.

Also, set the critical temperature below tjmax, because otherwise
thermal shutdown by the OS will never be triggered.
