[INET]: Fix netdev renaming and inet address labels
When re-naming an interface, the previous secondary address labels get lost e.g. $> brctl addbr foo $> ip addr add 192.168.0.1 dev foo $> ip addr add 192.168.0.2 dev foo label foo:00 $> ip addr show dev foo | grep inet inet 192.168.0.1/32 scope global foo inet 192.168.0.2/32 scope global foo:00 $> ip link set foo name bar $> ip addr show dev bar | grep inet inet 192.168.0.1/32 scope global bar inet 192.168.0.2/32 scope global bar:2 Turns out to be a simple thinko in inetdev_changename() - clearly we want to look at the address label, rather than the device name, for a suffix to retain.
