chore: enable unparam linter (#7174)

* chore: fix some doc comments for daqgl to match

* chore: remove some unused parameters

And also enable a linter to catch these in the future. `unparam` seems
to be optimized more heavily to avoid false positives, and is
significantly better at not bringing up weird interface cases that
revive seems to love.
