Execute the cmdparser asynchronously as part of the submission pipeline. Using our dma-fences, we can schedule execution after an asynchronous piece of work, so we move the cmdparser out from under the struct_mutex inside execbuf as run it as part of the submission pipeline. The same security rules apply, we copy the user batch before validation and userspace cannot touch the validation shadow. The only caveat is that we will do request construction before we complete cmdparsing and so we cannot know the outcome of the validation step until later -- so the execbuf ioctl does not report -EINVAL directly, but we must cancel execution of the request and flag the error on the out-fence.
