KVM: SVM: init_vmcb(): remove redundant save->cr0 initialization
The svm_set_cr0() call will initialize save->cr0 properly even when npt is enabled, clearing the NW and CD bits as expected, so we don't need to initialize it manually for npt_enabled anymore. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
