udf: use crc_itu_t from lib instead of udf_crc
As pointed out by Sergey Vlasov, UDF implements its own version of the CRC ITU-T V.41. Convert it to use the one in the library. Signed-off-by: Bob Copeland <me@bobcopeland.com> Cc: Sergey Vlasov <vsu@altlinux.ru> Signed-off-by: Jan Kara <jack@suse.cz>
