When detecting zero in 'dbs' field of CIP header, this packet streaming should be aborted because of avoiding division-by-zero. This is an error in an aspect of IEC 61883-1, thus protocol error. This commit use EPROTO instead of EIO. Actually, the returned value is not used for userspace and this commit has no effect.
