Karol Wachowski 54c49eca38 accel/ivpu: Prevent recovery work from being queued during device removal 
commit 69a79ada8e upstream.

Use disable_work_sync() instead of cancel_work_sync() in ivpu_dev_fini()
to ensure that no new recovery work items can be queued after device
removal has started. Previously, recovery work could be scheduled even
after canceling existing work, potentially leading to use-after-free
bugs if recovery accessed freed resources.

Rename ivpu_pm_cancel_recovery() to ivpu_pm_disable_recovery() to better
reflect its new behavior.

Fixes: 58cde80f45 ("accel/ivpu: Use dedicated work for job timeout detection")
