udf: Make udf_get_filename() return error instead of 0 length file name

Zero length file name isn't really valid. So check the length of the
final file name generated by udf_translate_to_linux() and return -EINVAL
instead of zero length file name. Update caller of udf_get_filename() to
not check for 0 return value.
