dmaengine: idxd: Set wq state to disabled in idxd_wq_disable_cleanup()
If we are calling idxd_wq_disable_cleanup(), the workqueue should be
in a disabled state. So set the workqueue state to IDXD_WQ_DISABLED so
that the state reflects that. Currently if there is a device failure,
and a software reset is attempted the workqueues will not be
re-enabled due to idxd_wq_enable() seeing that state as already being
IDXD_WQ_ENABLED.
