inet: Clear IP addresses when interface is set down
Clear interface IPv4 address by setting it to 0.0.0.0. IPv6
addresses are cleared automatically when the IFF_DYNAMIC flag is
set at the time the interface is brought down.
By removing the IP address and netmask, netlink properly reports
new addresses assigned by DHCPv4.
