mac80211: Update to backports-5.10.42

The removed patches were integrated upstream.

The brcmf_driver_work workqueue was removed in brcmfmac with kernel
5.10.42, the asynchronous call was covered to a synchronous call. There
is no need to wait any more.
This part was removed manually from this patch:
brcm/860-brcmfmac-register-wiphy-s-during-module_init.patch

-Subject: [PATCH] cfg80211: mitigate A-MSDU aggregation attacks
-
-Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the
-destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP)
-header, and if so dropping the complete A-MSDU frame. This mitigates
-known attacks, although new (unknown) aggregation-based attacks may
-remain possible.
-
-This defense works because in A-MSDU aggregation injection attacks, a
-normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means
-the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042
-header. In other words, the destination MAC address of the first A-MSDU
-subframe contains the start of an RFC1042 header during an aggregation
-attack. We can detect this and thereby prevent this specific attack.
-For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi
-Through Frame Aggregation and Fragmentation".
-
-Note that for kernel 4.9 and above this patch depends on "mac80211:
-properly handle A-MSDUs that start with a rfc1042 header". Otherwise
-this patch has no impact and attacks will remain possible.
