Zide Chen eed7309472 hv: update EPT when guests change MTRRs
MTRRs have no effect on the memory type used for an access to GPA.
This patch updates the EPT MT field according to the memory type
selected by MTRRs, which combines with the PAT, PCD and PWT bits
from the guest paging structures to determine the effective memory type
