netconfig: Move removal of DNSs out of IPv4 specific logic

Browse Source 
This way resolve_remove can be called once per interface and
remove IPv4 and IPv6 addresses at once.

In addition, this allows to remove the IP addresses and DNS
servers within the same main loop cycle. This will allow iwd
to make an attempt to remove the DNS servers on shutdown of iwd.
