If we do this before wiphy_register it will result in copying set flags (including IEEE80211_CHAN_DISABLED) to the orig_flags which is supposed to be persistent. We don't want this as regulatory change may result in enabling some channels. We shouldn't mess with orig_flags then (by changing them or ignoring them) so it's better to just take care of their proper values. This patch cleanups code a bit (by taking orig_flags more seriously) and allows further improvements like disabling really unavailable channels.
