hvm amd: Fix 32bit guest VM save/restore issues associated with SYSENTER MSRs

This patch turn-on SYSENTER MSRs interception for 32bit guest VMs on
AMD CPUs. With it, hvm_svm.guest_sysenter_xx fields always contain the
canonical version of SYSENTER MSRs and are used in guest save/restore.
The data fields in VMCB save area are updated as necessary.
