Dave Jiang 6b9a418d38 dmaengine: idxd: skip clearing device context when device is read-only ...

[ Upstream commit 1cd8e751d9 ]

If the device shows up as read-only configuration, skip the clearing of the
state as the context must be preserved for device re-enable after being
disabled.

Fixes: 0dcfe41e9a ("dmanegine: idxd: cleanup all device related bits after disabling device")
