The wq resources needs to be released before the kernel type is reset by
__drv_disable_wq(). With dma channels unregistered and wq quiesced, all the
wq resources for dmaengine can be freed. There is no need to wait until wq
is disabled. With the wq->type being reset to "unknown", the driver is
skipping the freeing of the resources.
Fixes: 0cda4f6986 ("dmaengine: idxd: create dmaengine driver for wq 'device'")
