In "drm/i915: Add support for mandatory cmdparsing" we introduced the concept of mandatory parsing. This allows the cmdparser to be invoked even when user passes batch_len=0 to the execbuf ioctl's. However, the cmdparser needs to know the extents of the buffer being scanned. Refactor the code to ensure the cmdparser uses the actual object size, instead of the incoming length, if user passes 0.
