mac80211: fix TX status reporting for ieee80211s
[ Upstream commit c42055105785580563535e6d3143cad95c7ac7ee ]
TX status reporting to ieee80211s is through ieee80211s_update_metric.
There are two problems about ieee80211s_update_metric:
1. The purpose is to estimate the fail probability
to a specific link. No need to restrict to data frame.
2. Current implementation does not work if wireless driver does not
pass tx_status with skb.
Fix this by removing ieee80211_is_data condition, passing
ieee80211_tx_status directly to ieee80211s_update_metric, and
putting it in both __ieee80211_tx_status and ieee80211_tx_status_ext.
