Subject: networkd: link - fix stopping v4 dhcpclient when the carrier is lost
The check for a running v4 dhcpclient was using DHCP_SUPPORT_V6 flag
instead of DHCP_SUPPORT_V4.
As a result, when the carrier was lost systemd was not cleaning up the
relevant addresses and routes. If the carrier was regained in another
environment, with a different subnet and gateway, the system would end
up with multiple addresses and default gateways and thus a broken
network configuration. This scenario can be easily reproduced with wifi
Forwarded: No, fixed upstream in 217 as side effect of commit ba179154.
