cfg80211: fix warning when using WEXT for IBSS
Fix kernel warning when using WEXT for configuring ad-hoc mode, e.g. "iwconfig wlan0 essid test channel 1" WARNING: at net/wireless/chan.c:373 cfg80211_chandef_usable+0x50/0x21c [cfg80211]() The warning is caused by an uninitialized variable center_freq1.
