accel/ivpu: Prevent recovery work from being queued during device removal

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

accel/ivpu: Prevent recovery work from being queued during device removal

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.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
