Summary of Changes

This is a small 2 patch set to fix a warning seen during boot of a kdump kernel on AMD systems where virtual apic logging is enabled.
A commit for dealing with enabled virtual apic logging during host resume, added a condition to check if virtual apic logging is already
running when the code goes to enable it. While there is some code during early iommu initialization that reset some features on the iommu,
this was not the case for virtual apic logging.
