net: use dev->name in netdev_pr* when it's available
netdev_name() returns dev->name only when the net_device is in NETREG_REGISTERED state. However, dev->name is always populated on creation, so we can easily use it. There are two cases when there's no real name - when it's an empty string or when the name is in form of "eth%d", then netdev_name() returns "unnamed net_device". CC: "David S.
