commit f478f33a93f9353dcd1fe55445343d76b1c3f84a upstream.
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.
