Fix Bug#12661768 UPDATE IGNORE CRASHES SERVER IF TABLE IS INNODB AND IT IS

Browse Source 
PARENT FOR OTHER ONE

Do not try to lookup key_nr'th key in 'table' because there may not be such
a key there. key_nr is the number of the key in the _child_ table name, not
in the parent table.

Instead just print the fields of the record that are covered by the first key
defined on the parent table.

This bug gets a better fix in MySQL 5.6, which is too risky for 5.1 and 5.5.
