Extend the applied solution with commit 14a3aacf517a9
("iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue")
to other cases where the station queues are also disabled and the related
lists are not emptied. In the same way, if some new element is added later
to the list in iwl_mvm_mac_wake_tx_queue, it can match with the old one
and produce the same commented BUG.
Again, in order to avoid this problem, we must also remove the related
lists when station queues are disabled.
