[nrf noup] zephyr: Restart DHCP for every association

krishna T · krish2718 · commit 4b9383525358 · 2023-07-27T23:52:33.000+05:30
After every successful association, restart DHCP to get a fresh lease.

For the initial association this avoid delay due to DHCP exponential
retries, and also handles the case where interface has changed IP
subnet.
