ext/sqlite3: fix wrong pointer types passed to the free list comparator.

SQLite3Stmt::close() and SQLite3Result::finalize() passed
php_sqlite3_stmt pointer types instead of sqlite3_stmt pointers
to zend_llist_del_element, causing the comparator to never match
and both methods to silently become no-ops.

Regression introduced in 5eae6d1 ("Don't store the object
zval directly").
