x86/mce/AMD: Fix LVT offset configuration for thresholding

Browse source

For processor families with the Scalable MCA feature, the LVT
offset for threshold interrupts is configured only in MSR
0xC0000410 and not in each per bank MISC register as was done in
earlier families.

Obtain the LVT offset from the correct MSR for those families.
