cfg80211: make wiphy index start at 0 again
The change to use atomic_inc_return() for assigning the wiphy index made the first wiphy index 1 instead of 0. This is fine, but we all habitually type "phy0" when we're testing, so make it go back to 0 instead of 1 by subtracting 1 from the index. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
