[PATCH v3 10/16] dmaengine: idxd: add descs_completed field for completion record

[Fenghua Yu]

From: Dave Jiang <dave.jiang@xxxxxxxxx>

The descs_completed field for a completion record is part of a batch
descriptor completion record. It takes the same location as bytes_completed
in a normal descriptor field. Add to expose to user.
