------------------

From: Nikita Shubin <n.shubin@xxxxxxxxx>

[ Upstream commit 5422145d0b749ad554ada772133b9b20f9fb0ec8 ]

Fix missing kmem_cache_destroy() for ioat_sed_cache in
ioat_exit_module().

Noticed via:

```
modprobe ioatdma
rmmod ioatdma
modprobe ioatdma
debugfs: Directory 'ioat_sed_ent' with parent 'slab' already present!
```
