NDIS to use ANSI function arguments and remove few unused code and debug

[ota_j.email.ne.jp]

Summary

Some code cleanup I worked on when I was fixing issues in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213237.
In the bug report, I wanted to focus on functionality fix and did not include these changes.

Test Plan

Use NDIS wireless.
(I will update and post which one I use when I get a chance to use the laptop with NDIS wireless)
