KVM: VMX: Skip #PF(RSVD) intercepts when emulating smaller maxphyaddr
As part of smaller maxphyaddr emulation, kvm needs to intercept present page faults to see if it needs to add the RSVD flag (bit 3) to the error code. However, there is no need to intercept page faults that already have the RSVD flag set. When setting up the page fault intercept, add the RSVD flag into the #PF error code mask field (but not the #PF error code match field) to skip the intercept when the RSVD flag is already set.
