dmaengine: idxd: Remove redundant variable cdev_ctx

Browse Source 
Variable cdev_ctx is set to '&ictx[wq->idxd->data->type]' but this
value is not used, hence it is a redundant assignment and can be
removed.

Clean up the following clang-analyzer warning:

drivers/dma/idxd/cdev.c:300:2: warning: Value stored to 'cdev_ctx' is
never read [clang-analyzer-deadcode.DeadStores].
