BUG/MINOR: debug: remove the trailing \n from BUG_ON() statements

These ones were added by mistake during the change of the cfgparse
mechanism in 3.1, but they're corrupting the output of "debug counters"
by leaving stray ']' on their own lines. We could possibly check them
all once at boot but it doens't seem worth it.

This should be backported to 3.1.
