Subject[30/45] hwmon: (coretemp) Fix oops on CPU offlining
3.0-stable review patch.  If anyone has any objections, please let me know.


This is for stable kernel branch 3.0 only. Previous and later versions
have different code paths and are not affected by this bug.

This is the same fix as "hwmon: (coretemp) Fix oops on driver load"
but for the CPU offlining case. Sorry for missing it at first.
