4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Malcolm Priestley <tvboxspy@xxxxxxxxx>
commit 95d93e271d920dfda369d4740b1cc1061d41fe7f upstream.
TID 7 is a valid value for QoS IEEE 802.11e.
The switch statement that follows states 7 is valid.
Remove function IsACValid and use the default case to filter
invalid TIDs.
