KVM: SVM: Emulate SYSENTER RIP/RSP behavior for all Intel compat vCPUs
Emulate bits 63:32 of the SYSENTER_R{I,S}P MSRs for all vCPUs that are
compatible with Intel's architecture, not just strictly vCPUs that have
vendor==Intel. The behavior of bits 63:32 is architecturally defined in
the SDM, i.e. not some uarch specific quirk of Intel CPUs.
