This fixes a failure in vb2_qbuf in user pointer mode where __qbuf_userptr checks if the buffer queued by userspace is large enough. The failure would happen if coda_queue_setup was called with empty fmt (and thus set the expected buffer size to the maximum resolution), and userspace queues buffers of smaller size - corresponding to the negotiated dimensions - were queued. Explicitly setting sizeimage to the value negotiated via s_fmt fixes the issue.
