From: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>
commit 8f38302c0be2d2daf3b40f7d2142ec77e35d209e upstream.
Commit 8c5fbf1a7231 ("KVM/nSVM: Use the new mapping API for mapping guest
memory") broke nested SVM completely: kvm_vcpu_map()'s second parameter is
GFN so vmcb_gpa needs to be converted with gpa_to_gfn(), not the other way
around.
