[PATCH 1/1] dmaengine: idxd: remove unused variable 'cdev_ctx'

[Zhen Lei]

GCC reports the following warning with W=1:

drivers/dma/idxd/cdev.c:298:28: warning:
 variable 'cdev_ctx' set but not used [-Wunused-but-set-variable]
  298 |  struct idxd_cdev_context *cdev_ctx;
      |                            ^~~~~~~~

The variable 'cdev_ctx' is not used, remove it to fix the warning.
