[PATCH] KVM: nVMX: set rflags to specify success in handle_invvpid() default case

[linmiaohe]

From: Miaohe Lin <linmiaohe@xxxxxxxxxx>

In handle_invvpid() default case, we just skip emulated instruction and
forget to set rflags to specify success. This would result in indefinite
rflags value and thus indeterminate return value for guest.
