iwlagn: fix TID use bug
commit 9a215e40d70ae63762963ab3ccc7f31dd966dc6a upstream.
The driver everywhere uses max TID count as 9,
which is wrong, it should be 8.
I think the reason it uses 9 here is off-by-one
confusion by whoever wrote this. We do use the
value IWL_MAX_TID_COUNT for "not QoS/no TID"
but that is completely correct even if it is 8
and not 9 since 0-7 are only valid.
As a side effect, this fixes the following bug:
Open BA session requested for 00:23:cd:16:8a:7e tid 8
