[PATCH] Silence debug prints when using adhoc mode

[Mikko Rapeli <mikko.rapeli@iki.fi>]

This is flooded to syslog quite a few times when connecting to another
Linux box in adhoc mode. Syslog files fill up the disk fast:

$ dmesg | tail -10
[ 1986.772018] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)
[ 1986.776149] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)

[ 1986.808072] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)

Tested on a Thinkpad T60 with Intel Corporation PRO/Wireless 3945ABG [Golan]
Network Connection (rev 02) running vanilla 2.6.34 kernel.
