iwlwifi: mvm: fix references to first_agg_queue in DQA mode
In DQA mode, first_agg_queue is initialized to
IWL_MVM_DQA_MIN_DATA_QUEUE. This causes two bugs in the tx response
flow:
1. When TX fails, we set IEEE80211_TX_STAT_AMPDU_NO_BACK regardless
if we actually have aggregation open on the queue. This causes
mac80211 to send a BAR frame even though there is no aggregation
open.
Fix that by simply checking the AMPDU flag that is set on by
mac80211 for AMPDU packets.
2. When reclaiming frames in aggregation mode, we reclaim based on
scheduler ssn and not the SN.
The reason is that scheduler ssn may be ahead of SN due to a hole
in the BA window that was filled.
However, if we have aggregations open on IWL_MVM_DQA_BSS_CLIENT_QUEUE
the reclaim flow will still go to the code of non-aggregation
instead of the aggregation code since IWL_MVM_DQA_BSS_CLIENT_QUEUE
is smaller than IWL_MVM_DQA_MIN_DATA_QUEUE, although it is a valid
aggregation queue.
Fix that by always using the aggregation reclaim code by default in
DQA mode (currently it is implicitly used by default for all queues
except the reserved BSS queue).
