Summary

We used to call lkpi_wake_tx_queues() for all queues early on in order
to make sure they are ready. Turns out whatever logic in iwlwifi
startup is working correctly these days under LinuxKPI so this is no
longer needed. As the comment indicated the "workaround" did not
always work. Disable it for now.

Part of the actual fix seems to be to properly classify Non-QOS non-data
frames (mgmt and ctl frames for now, unless we have to be even more
careful in the future about certain sub-types) as TID 7/VO.
Contrary to net80211 we must not promote PAE frames.

(based on out-of-band debugging there are more issues).

I am leaving this comment to let people know that review of this should continue anyway.

Shall correct the typo first before committing.

Tested in branches of main, stable/14 and stable/13. No regression found.
