dmaengine: idxd: fix resource leak on dmaengine driver disable
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.
