I've linked a proposed patch which reverts commit 97595710b7. Revert
doesn't apply cleanly so I massaged the patch to fit.

Here is confirmation that it works as expected:

Title:
  Regression: Persistent net names via /etc/udev/rules.d/70-persistent-
  net.rules fail

Status in “linux” package in Ubuntu:
  Invalid
Status in “systemd” package in Ubuntu:
  Triaged

Bug description:
  systemd-udev 204.

  Installing 13.10 amd64 on a multi-homed server. There are 5 ethernet
  interfaces, one on the mobo and four on a PCIe adapter.

  udev created "/etc/udev/rules.d/70-persistent-net.rules" and I later
  edited the NAME= assignments to match the device naming required.

  These rules are apparently ignored but it transpires that the kernel
  is returning -EEXIST from net/core/dev.c::dev_get_valid_name().

  This renaming works in earlier versions, specifically on a 12.04 LTS
  server with ten Ethernet interfaces, and is therefore a regression.
