[PATCH v2 0/3] FD close cleanup for XE

[Daniel Charles <daniel.charles@intel.com>]

This series adds the suggested logic to synchronously wait for the queue
kill to complete on FD close. This is needed to avoid a race condition
where the scheduler may still be processing messages for a queue that
has been closed, which can lead to errors.

This series includes a rebase of patch

fe73d8e1cdfac drm/xe: Disable scheduling early on FD close to avoid CAT error cascade

v2:
    - Bound the wait with a timeout, GT reset on timeout (Sashiko, Matt B)
    - Drop the flush_work() loop (Matt B)
    - Use xe_assert() for the killed-queue check (Matt B)
    - Merge the put loop into the kill_sync loop (Matt B)
