drop 1 patch from queue-5.15 and queue-5.10 based on RC review feedback

Dropped patches:

- "wifi: cfg80211: cancel pmsr_free_wk in cfg80211_pmsr_wdev_down"
  Queues: 5.15, 5.10
  Reason: deadlock — cancel_work_sync(&wdev->pmsr_free_wk) called while
  holding wdev->mtx, but the work function cfg80211_pmsr_free_wk() also
  acquires wdev->mtx via wdev_lock(). The locking model differs between
  5.10/5.15 (wdev mutex) and mainline (wiphy lock), making this backport
  unsafe.

-[ Upstream commit 6dccbc9f3e1d38565dff7730d2b7d1e8b16c9b09 ]
-
-When the nl80211 socket that originated a PMSR request is
-closed, cfg80211_release_pmsr() sets the request's nl_portid
-to zero and schedules pmsr_free_wk to process the abort
-asynchronously. If the interface is concurrently torn down
-before that work runs, cfg80211_pmsr_wdev_down() calls
-cfg80211_pmsr_process_abort() directly. However, the already-
-scheduled pmsr_free_wk work item remains pending and may run
-after the interface has been removed from the driver. This
-could cause the driver's abort_pmsr callback to operate on a
-torn-down interface, leading to undefined behavior and
-potential crashes.
-
-Cancel pmsr_free_wk synchronously in cfg80211_pmsr_wdev_down()
-before calling cfg80211_pmsr_process_abort(). This ensures any
-pending or in-progress work is drained before interface teardown
-proceeds, preventing the work from invoking the driver abort
-callback after the interface is gone.
