r8169: re-establish support for RTL8401 chip version

BugLink: https://bugs.launchpad.net/bugs/1879759
[ Upstream commit 1f8492df081bd66255764f3ce82ba1b2c37def49 ]

r8169 never had native support for the RTL8401, however it reportedly
worked with the fallback to RTL8101e [0]. Therefore let's add this
as an explicit assignment.
