KVM: nVMX: pass PFERR_USER_MASK to MMU on EPT violations

For EPT, PFERR_USER_MASK refers not to the CPL of the guest,
but to the AND of the U bits encountered while walking guest
page tables; this is consistent with how MBEC differentiates
between XS and XU.  This is available through the
"advanced vmexit information for EPT violations" feature.
