dmaengine: idxd: fix device cleanup on disable
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.
