cifs: Change translation of STATUS_NOT_A_REPARSE_POINT to -ENODATA 



STATUS_NOT_A_REPARSE_POINT indicates that object does not have reparse point
buffer attached, for example returned by FSCTL_GET_REPARSE_POINT.

Currently STATUS_NOT_A_REPARSE_POINT is translated to -EIO. Change it to
-ENODATA which better describe the situation when no reparse point is set.
