Hi,

During testing some not so happy code paths in a debugging (lockdep,
kmemleak, etc) kernel, found a few issues.

There's still a crash that happens when doing a PCI unbind, but I
don't have a patch at this time.

Cheers,

Changes in v2:
- Fixed messing up the definition of FLR (Function Level
  Reset) (Nathan Lynch)
- Simplified callers of idxd_device_config(), moved a common check,
  and locking to inside the function (Dave Jiang);
- For idxd DMA backend, ->terminate_all() now flushes all pending
  descriptors (Dave Jiang);
- For idxd DMA backend, ->device_synchronize() now waits for submitted
  operations to finish (Dave Jiang);
- Link to v1: https://lore.kernel.org/r/20250804-idxd-fix-flr-on-kernel-queues-v3-v1-0-4e020fbf52c1@intel.com
