Xiaoguang Wu b4f1e5aa85 hv: iommu: disable snoop bit in EPT-PTE/SL-PTE ...

Due to the fact that i915 iommu doesn't support snoop, hence it can't
access memory when the SNOOP bit of Secondary Level page PTE (SL-PTE)
is set, this will cause many undefined issues such as invisible cursor
in WaaG etc.

Current hv design uses EPT as Scondary Leval Page for iommu, and this
patch removes the codes of setting SNOOP bit in both EPT-PTE and SL-PTE
to avoid errors.

And according to SDM 28.2.2, the SNOOP bit (11th bit) will be ignored
by EPT, so it will not affect the CPU address translation.
