iwlwifi: mvm: don't mark TIDs that are not idle wrt BA as inactive

Browse Source 
A TID may not have traffic but still have a BA agreement
active (or being setup / torn down) since a BA agreement
can be triggered by a debugfs hook.
Just avoid to consider such a TID as inactive to make the
logic safer.
