[Bug] - object versions concurrent upload

[jonaustin09]

Describe the bug Versioning implementation doesn't correctly handle multiple concurrent object versions upload requests. Some of them cause internal server errors. e.g Internal Error, set content-type attr: xattr.Set test-bucket-1/my-obj user.content-type: no such file or directory

To Reproduce Run the following integration test against the gateway:

func Concurrent_upload_object_versions(s *S3Conf) error {
	testName := "Concurrent_upload_object_versions"
	return actionHandler(s, testName, func(s3client *s3.Client, bucket string) error {
		obj := "my-obj"
		versionCount := 5
		// Channel to collect errors
		errCh := make(chan error, versionCount)

		uploadVersion := func(wg *sync.WaitGroup) {
			defer wg.Done()

			ctx, cancel := context.WithTimeout(context.Background(), shortTimeout)
			res, err := s3client.PutObject(ctx, &s3.PutObjectInput{
				Bucket: &bucket,
				Key:    &obj,
			})
			cancel()
			if err != nil {
				// Send error to the channel
				errCh <- err
				return
			}

			fmt.Printf("uploaded object successfully: versionId: %v\n", *res.VersionId)
		}

		wg := &sync.WaitGroup{}
		wg.Add(versionCount)

		for i := 0; i < versionCount; i++ {
			go uploadVersion(wg)
		}

		wg.Wait()
		close(errCh)

		// Check if there were any errors
		for err := range errCh {
			if err != nil {
				fmt.Printf("error uploading an object: %v\n", err.Error())
				return err
			}
		}

		// List object versions after all uploads
		ctx, cancel := context.WithTimeout(context.Background(), shortTimeout)
		res, err := s3client.ListObjectVersions(ctx, &s3.ListObjectVersionsInput{
			Bucket: &bucket,
		})
		cancel()
		if err != nil {
			return err
		}

		if len(res.Versions) != versionCount {
			return fmt.Errorf("expected %v object versions, instead got %v", versionCount, len(res.Versions))
		}

		return nil
	}, withVersioning())
}

Expected behavior The test should successfully pass without any errors.
