KVM: x86: Define RMP page fault error bits for #NPF
When SEV-SNP is enabled globally, the hardware places restrictions on all
memory accesses based on the RMP entry, whether the hypervisor or a VM,
performs the accesses. When hardware encounters an RMP access violation
during a guest access, it will cause a #VMEXIT(NPF).
See APM2 section 16.36.10 for more details.
