There is no a need to free the current thd->lex here.
- In the majority of the cases restore_lex() is called
on success and thd->lex does not need to be deleted.
- In cases when restore_lex() is called on error,
e.g. from sp_create_assignment_instr(), thd->lex is
already linked to some sp_instr_xxx (using sp_lex_keeper).
Note, we don't get to here in case of a syntax error
when the current thd->lex is not yet completely
initialized and linked. It gets automatically deleted
by the Bison %destructor in sql_yacc.yy.
