[PATCH] KVM: vmx: Set msr bitmap correctly if vcpu is in guest mode

In commit 3af18d9c5fe9 ("KVM: nVMX: Prepare for using hardware MSR bitmap"), we are setting MSR_BITMAP in prepare_vmcs02 if we should use hardware. This is not enough since the field will be modified by following vmx_set_efer. Fix this by setting vmx_msr_bitmap_nested in vmx_set_msr_bitmap if vcpu
