evgen@sunlight.local 629c12316d Bug#25126: Wrongly resolved field leads to a crash. ...

When the ORDER BY clause gets fixed it's allowed to search in the current
item_list in order to find aliased fields and expressions. This is ok for a
SELECT but wrong for an UPDATE statement. If the ORDER BY clause will
contain a non-existing field which is mentioned in the UPDATE set list
then the server will crash due to using of non-existing (0x0) field.

When an Item_field is getting fixed it's allowed to search item list for
aliased expressions and fields only for selects.
