4.18-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit cb59bc14e830028d2244861216df038165d7625d ]
If the TDLS setup happens over a connection to an AP that
doesn't have QoS, we nevertheless assign a non-zero TID
(skb->priority) and queue mapping, which may confuse us or
drivers later.
Fix it by just assigning the special skb->priority and then
using ieee80211_select_queue() just like other data frames
would go through.
