network: check the received interface name is actually new
For some reasons I do not know, on interface renaming, kernel once send
netlink message with old interface name, and then send with new name.
If eth0 is renamed, and then new interface appears as eth0, then the
message with the old name 'eth0' makes the interface enters failed
state.
To ignore such invalid(?) rename event messages, let's confirm the
received interface name.
