mac80211: Add patches which were added later

These patches were added after the new matches structure for the
mac80211 package was created. All the deleted patches are already
integrated in kernel 4.19-rc4.

-The TXQ teardown code can reference the vif data structures that are
-stored in the netdev private memory area if there are still packets on
-the queue when it is being freed. Since the TXQ teardown code is run
-after the netdevs are freed, this can lead to a use-after-free. Fix this
-by moving the TXQ teardown code to earlier in ieee80211_unregister_hw().

-When building building AMSDU from non-linear SKB, we hit a

-Instead, put the padding at the head of the next subframe.

-Subject: [PATCH] mac80211: fix a race between restart and CSA flows
-
-We hit a problem with iwlwifi that was caused by a bug in
-mac80211. A bug in iwlwifi caused the firwmare to crash in
-certain cases in channel switch. Because of that bug,
-drv_pre_channel_switch would fail and trigger the restart
-flow.
-Now we had the hw restart worker which runs on the system's
-workqueue and the csa_connection_drop_work worker that runs
-on mac80211's workqueue that can run together. This is
-obviously problematic since the restart work wants to
-reconfigure the connection, while the csa_connection_drop_work
-worker does the exact opposite: it tries to disconnect.
-
-Fix this by cancelling the csa_connection_drop_work worker
-in the restart worker.
-
-Note that this can sound racy: we could have:
-
-driver   iface_work   CSA_work   restart_work
-+++++++++++++++++++++++++++++++++++++++++++++
-              |
- <--drv_cs ---|
-<FW CRASH!>
--CS FAILED-->
-              |                       |
-              |                 cancel_work(CSA)
-           schedule                   |
-           CSA work                   |
-                         |            |
-                        Race between those 2
-
-But this is not possible because we flush the workqueue
-in the restart worker before we cancel the CSA worker.
-That would be bullet proof if we could guarantee that
-we schedule the CSA worker only from the iface_work
-which runs on the workqueue (and not on the system's
-workqueue), but unfortunately we do have an instance
-in which we schedule the CSA work outside the context
-of the workqueue (ieee80211_chswitch_done).
-
-Note also that we should probably cancel other workers
-like beacon_connection_loss_work and possibly others
-for different types of interfaces, at the very least,
-IBSS should suffer from the exact same problem, but for
-now, do the minimum to fix the actual bug that was actually
-experienced and reproduced.

-Subject: [PATCH] mac80211: don't Tx a deauth frame if the AP forbade Tx
-
-If the driver fails to properly prepare for the channel
-switch, mac80211 will disconnect. If the CSA IE had mode
-set to 1, it means that the clients are not allowed to send
-any Tx on the current channel, and that includes the
-deauthentication frame.
-
-Make sure that we don't send the deauthentication frame in
-this case.
-
-In iwlwifi, this caused a failure to flush queues since the
-firmware already closed the queues after having parsed the
-CSA IE. Then mac80211 would wait until the deauthentication
-frame would go out (drv_flush(drop=false)) and that would
-never happen.
