This allows us to know is the queue is empty. To get access to this private area, we use fw_id_to_mac_id that maps sta_id (index of the STA in fw table) to ieee80211_sta. When the STA exists in fw, but not in mac80211, we set an ERR ptr in fw_id_to_mac_id. But if we first set an ERR ptr to fw_id_to_mac_id, and only then flush the queues, then we won't be able to access the sequence numbers in ieee80211_sta from the reclaim flow. This means that we will never be able to release an AGG queue when a station is deleted. So first, flush the queue. That will let the reclaim flow call iwl_mvm_check_ratid_empty which will disable the AGG queue as needed, and only then, remove the mapping in fw_id_to_mac_id.
