wifi: iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue (other cases)

BUGs like this are still reproducible:

[   31.509616] list_add corruption. prev->next should be next (ffff8f8644242300), but was ffff8f86493fd300. (prev=ffff8f86493fd300).

So, it is necessary to extend the applied solution with commit 14a3aacf517a9
("iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue")
to all other cases where the station queues are invalidated and the related
lists are not emptied. Because, otherwise as before, 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.

That is, in order to avoid this problem completely, we must also remove the
related lists for the other cases when station queues are invalidated.
