mac80211: fix channel context iteration
During suspend/resume channel contexts might be iterated even if they haven't been re-added to the driver, keep track of this and skip them in iteration. Also use the new status for sanity checks. Also clarify the fact that during HW restart all contexts are iterated over (thanks Eliad.) Signed-off-by: Johannes Berg <johannes.berg@intel.com>
