This commit fixes the following issue:

Issue Summary: An error occurs when attempting to delete images with non-existing ZFS layers, resulting in unintended behavior during image removal in Podman.

Steps to reproduce:

Preconditions:

• A system running ZFS file system (tested on a FreeBSD machine).
• ZFS dataset zroot/containers is mounted on /var/db/containers
• [optional] No existing images and containers (recommended for easier identification of the pulled image in the following steps)

Steps:

# Replace <image> with any other images, such as docker.io/dougrabson/hello
$ podman pull <image>

# Check the dataset name created under `zroot/containers`
$ zfs list -d 1 zroot/containers

# Manually destroy dataset
$ zfs destroy zroot/containers/<dataset_name>

# Error may occur; this might be expected
$ podman images <image>

# Manually remove the corrupted image
$ podman rmi <image> --force

# Error reproduces here - not intended
$ podman images <image>

Note: For recovery, you can recreate the dataset with the same name, and then remove the image with Podman.
