[ Upstream commit 12e45e89556d7a532120f976081e9e7582addd2b ]
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.
