dmaengine: idxd: fix device cleanup on disable
[ 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.
Fixes: 0f225705cf65 ("dmaengine: idxd: fix wq settings post wq disable")
