On building the route there is an assumption that the destination could be local. In this case loopback_dev is used to get the address. If the address is still cannot be retrieved dn_route_output_slow returns EADDRNOTAVAIL with loopback_dev reference taken. Cannot find hash for the fixes tag because this code was introduced long time ago. I don't think that this bug has ever fired but the patch is done just to have a consistent code base.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
