cfg80211: fix possible memory leak in cfg80211_iter_combinations()
'limits' is malloced in cfg80211_iter_combinations() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak. Fixes: 0c317a02ca98 ("cfg80211: support virtual interfaces with different beacon intervals") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
