dev_dbg_reatelimited() without DEBUG printed "217078 callbacks

NACK. I don't think that's correct behavior. After that patch it kills
all output of dev_dbg_ratelimited(). If I use dynamic debugs and order
debugs, I expect to see debugs as earlier.
I did test module in order to demonstrate problem. Here it is:
http://git.linuxtv.org/anttip/media_tree.git/shortlog/refs/heads/dev_dbg_ratelimited
There is also file named: test_results.txt
It contains 4 test cases:
1) without that patch & without module dynamic debug
2) without that patch & module dynamic debug ordered
3) with that patch & without module dynamic debug
4) with that patch & module dynamic debug ordered
