back-ported the patch for bug #13256831 from mysql-5.6 code line.

  Here's the comment this patch was provided with:

  Fixed bug#13256831 - ERROR 1032 (HY000): CAN'T FIND RECORD.

  This bug only occurs if a user tries to update a base table using
  an updatable view and this view was created as a join for which
  the clause 'WITH CHECK OPTION' was specified.

  The reason for the bug was that when such an update was
  executed, row positions were not properly handled for tables
  that were not updated but had constraints that had to be
  checked due to the 'WITH CHECK OPTION' clause.

  The reason for the bug was that when such update is executed
  then for tables specified in the view definition and
  also listed in the 'WITH CHECK OPTION' clause the positioning to
  row being updated is not performed.
