Summary

After I MFC D51433, Mark Millard raised concerns about this change:
https://lists.freebsd.org/archives/dev-commits-src-branches/2025-August/023040.html

I have limited knowledge of this code, but as I understand it, their concerns apply when the user configure a bad address file and this file exist but is empty (0 lines, 0 bytes). If so, I propose to adjust the code this way to explicitly show what valid pre-conditions put a value in *list / *end, and otherwise both are set to NULL.
