IFNULL(inet6_not_null_expr, 'foo') erroneously set its nullability to NOT NULL. Fix: - Moving the line "maybe_null= args[1]->maybe_null" before the call of fix_length_and_dec2(), so the call of Type_handler method Item_hybrid_func_fix_attributes() can reset it when desired. - Fixing Type_handler_inet6::Item_hybrid_func_fix_attributes() to ignore args[0] when detecting nullability of IFNULL().
