[PATCH 19/35] KVM: SVM: init_vmcb(): remove redundant save->cr0 initialization

From: Eduardo Habkost <ehabkost@redhat.com>

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.
