vpp: T8979: Fix defunct interface retaining IP addresses after crash
flush_ip() used flush_addr(label=iface_name) which only matches addresses
whose label equals exactly the interface name. Secondary IP addresses are
assigned with :N suffixed labels (e.g. defunct_eth0:2, defunct_eth0:3)
and are not matched, so they remain on the interface.
Fix by flushing addresses by interface index instead of label, which
removes all addresses regardless of their label.
