ipv4: Check return of dev_set_allmulti allmulti might overflow. Commit: "netdevice: Fix promiscuity and allmulti overflow" in net-next makes dev_set_promiscuity/allmulti return error number if overflow happened. Here, we check the positive increment for allmulti to get error return. PS: For unwinding tunnel creating, we let ipip->ioctl() to handle it.
