CVE-2024-39493

crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak

In the Linux kernel, the following vulnerability has been resolved:

crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak

Using completion_done to determine whether the caller has gone
away only works after a complete call.  Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.

Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.
