KVM: x86: svm: remove unneeded nested_enable_evmcs() hook
Since commit 5158917c7b019 ("KVM: x86: nVMX: Allow nested_enable_evmcs to be NULL") the code in x86.c is prepared to see nested_enable_evmcs being NULL and in VMX case it actually is when nesting is disabled. Remove the unneeded stub from SVM code. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Reviewed-by: Jim Mattson <jmattson@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
