You've got an old set of udev network device rename rules. The master
interface has the same MAC address as the real interface, and it is
created first. So the old udev rule (which only keys on the MAC
address) renames it to eth3. Then the real interface is created, udev
sees that it has already renamed an interface with that MAC and gives
it the wlan0_rename name.

If you delete the generated rename rules, it should create the correct
ones on the next boot. Alternately, you could add a ATTRS{type}="1"
selector to your current rule. Debian puts these autogenerated udev
rules in /etc/udev/rules.d/z25_persistent-net.rules. Other
distributions may vary slightly.
