KVM: x86/mmu: Set Dirty bit for new SPTEs, even if _hardware_ A/D bits are disabled
When making a SPTE, set the Dirty bit in the SPTE as appropriate, even if
hardware A/D bits are disabled. Only EPT allows A/D bits to be disabled,
and for EPT, the bits are software-available (ignored by hardware) when
A/D bits are disabled, i.e. it is perfectly legal for KVM to use the Dirty
to track dirty pages in software.
