Description:
------------
Some SplFileInfo methods don't restore original error handler in exceptional cases.
This leads to memory leaks.

Test script:
---------------
<?php
class BadSplFileInfo extends SplFileInfo {
    public function __construct() {
    }
}
$x = new BadSplFileInfo();
set_error_handler(function ($type, $msg, $file, $line, $context = []) {
    echo "ops\n";
});
try {
    var_dump($x->getLinkTarget());
} catch (Throwable $e) {
    echo $e->getMessage() . "\n";
}
?>

Expected result:
----------------
Object not initialized


Actual result:
--------------
Object not initialized
