[PATCH] dmaengine: idxd: fix device cleanup on disable

[Dave Jiang]

There are certain parts of WQ that needs to be cleaned up even after WQ is
disabled during the device disable. Those are the unchangeable parts for a
WQ when the device is still enabled. Move the cleanup outside of WQ state
check. Remove idxd_wq_disable_cleanup() inside idxd_wq_device_reset_cleanup()
since only the unchangeable parts need to be cleared.
