x86/mce: Convert static array of pointers to per-cpu variables
When I previously fixed up the mce_device code, I used a static array of
the pointers. It was (rightfully) pointed out to me that I should be
using the per_cpu code instead.
This patch converts the code over to that structure, moving the variable
back into the per_cpu area, like it used to be for 3.2 and earlier.
