[PATCH] dmaengine: ioatdma: Fix missing kmem_cache_destroy()

[Nikita Shubin via B4 Relay <devnull+n.shubin.yadro.com@xxxxxxxxxx>]

From: Nikita Shubin <n.shubin@xxxxxxxxx>

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!
```

Fixes: c0f28ce66ecf ("dmaengine: ioatdma: move all the init routines")
