hwmon: (coretemp) Remove obsolete temp_data->valid
Checking for the valid bit of IA32_THERM_STATUS is removed in commit
bf6ea084eb
("hwmon: (coretemp) Do not return -EAGAIN for low
temperatures"), and temp_data->valid is set and never cleared when the
temperature has been read once.
Remove the obsolete temp_data->valid field.
