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).
