dmaengine: idxd: Fix freeing the allocated ida too late
[ Upstream commit c311f5e9248471a950f0a524c2fd736414d98900 ]
It can happen that when the cdev .release() is called, the driver
already called ida_destroy(). Move ida_free() to the _del() path.
We see with DEBUG_KOBJECT_RELEASE enabled and forcing an early PCI
unbind.
