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

Dropped patches:

- "dmaengine: idxd: Fix not releasing workqueue on .release()"
  Queues: 5.15
  Reason: causes double destroy_workqueue() (UAF) on idxd_remove in 5.15 because the upstream refactor a409e919ca32 that removed destroy_workqueue() from idxd_remove() is not backported to 5.15
  Report: https://lore.kernel.org/stable/72718777-af7f-4d1a-902d-04e765a8e8aa@oracle.com/
