Please revert "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb" from all stable kernels

[Hans de Goede]

Hi Greg (et all),

Note several people are already working on this, so you may already have a request for this.

The "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb" commit which has been
added to several stable kernels (at least to 5.4.y and 5.7.y, but likely also to others)
is breaking networking for people with an ath9k card.

A revert has been submitted upstream, but it does not seem to have found it way
upstream yet. It has been cherry-picked by the Arch people:

https://git.archlinux.org/linux.git/commit/?h=v5.7.8-arch1&id=1a32e7b57b0b37cab6845093920b4d1ff94d3bf4

So if you want to credit some of the original people working on fixing this,
you can find the revert submitted upstream there.

Reverting this fixes / also see:

https://bugzilla.redhat.com/show_bug.cgi?id=1848631

Regards,

Hans
