This is to avoid the Channel Center Frequency Segment 2
in broadcasted VHT operation element contains the non-zero
value for non 80+80 MHz that may failed the comparison of
cfg80211_chandef_identical.
This is tested with Bob's patches related to VHT mesh support.

I suppose I'll squash this into the appropriate of Bob's patches :)
