Thanks for your answer Jouni.

I supposed the reason was wpa_supplicant because I used grep
to look into the code of wpa_supplicant and iwlwifi (my wifi
driver) and the only result comes from wpa_supplicant:
$ grep -r -A3 ": WMM queue=" wpa_supplicant-0.5.8/ iwlwifi-1.2.23/
wpa_supplicant-0.5.8/mlme.c:            wpa_printf(MSG_DEBUG,
"MLME: WMM queue=%d aci=%d acm=%d "
wpa_supplicant-0.5.8/mlme.c-                       "aifs=%d
cWmin=%d cWmax=%d burst=%d",
wpa_supplicant-0.5.8/mlme.c-                       queue, aci,
acm, params.aifs, params.cw_min,
wpa_supplicant-0.5.8/mlme.c-                      
params.cw_max, params.burst_time);

As I got a result, I didn't think looking into the kernel's
code. Now, after your answer I've tried it and I get: 
$ grep -r  ": WMM queue=" /usr/src/linux/
/usr/src/linux/net/mac80211/ieee80211_sta.c:           
printk(KERN_DEBUG "%s: WMM queue=%d aci=%d acm=%d aifs=%d "

So it must be the reason I get these messages.

Probably this mail list is not the best place to look for help
but, what I don't understand is, if it is a debug information
of net/mac80211 and I have disabled debugging, why it gets logged?
$ grep MAC80211_DEBUG /usr/src/linux/.config
# CONFIG_MAC80211_DEBUG is not set
