hwmon: (coretemp) Remove redundant pdata->cpu_map[]

hwmon: (coretemp) Remove redundant pdata->cpu_map[]

pdata->cpu_map[] saves the mapping between cpu core id and the index in
pdata->core_data[]. This is used to find the temp_data structure using
cpu_core_id, by traversing the pdata->cpu_map[] array. But the same goal
can be achieved by traversing the pdata->core_temp[] array directly.

Remove redundant pdata->cpu_map[].

No functional change.
