Since these counters can only be read through debugfs, there's very little point in maintaining them all the time. However, even just making them depend on debugfs is pointless - they're not normally used. Additionally a number of them aren't even concurrency safe. Move them under MAC80211_DEBUG_COUNTERS so they're normally not even compiled in. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

possible, as drafts leave a number of identifiers to be defined after
