device: restart DHCP only for devices that are active or activating

do_sleep_wake() tries to restart DHCP for all devices, even ones that
are disconnecting. When a device is disconnecting, it still has a DHCP
client instance but we shouldn't restart it because it makes no sense;
and especially, the device could be already removed.
