CLEANUP: debug: remove the now unused counter argument to complain()

CLEANUP: debug: remove the now unused counter argument to complain()

Let's drop it before someone has the idea to use it again.

We take this opportunity for swapping complain()'s arguments which were
really poorly ordered since we're really passing a context first, so the
calls read better this way, particularly since we plan to add more.

This drops another 4 kB of code due to the number of calls.
