iwlwifi: mvm: clarify stop_count, remove transport_stopped
The queue handling is a bit unclear - we have an array for stop_count[IWL_MAX_HW_QUEUES] but indices really are the mac80211 queue numbers. Change the array to be only of the right size for mac80211 queues (IEEE80211_MAX_QUEUES) and rename it to be clearer. While at it, also remove the unused transport queue stop bitmap in mvm.
