Fixed Bug#12621017 - CRASH IF A SP VARIABLE IS USED IN THE LIMIT CLAUSE OF A
SET STATEMENT.
Server built with debug asserts, without debug crashes if a user tries
to run a stored procedure that constains query with subquery that include
either LIMIT or LIMIT OFFSET clauses.
The problem was that Item::fix_fields() was not called for the items
representing LIMIT or OFFSET clauses.
The solution is to call Item::fix_fields() right before evaluation in
st_select_lex_unit::set_limit().
