AVC denials messages to unmount operation when stopping a podman container

What were you trying to do that didn't work?

• Podman stop does not unmount a mount point.

  Please provide the package NVR for which bug is seen:

Red Hat Enterprise Linux 8.8
Podman 4.4.1

How reproducible:

Steps to reproduce

1.  Start a podman contianer
2. podman run -d --name container_abc  -v /mnt/abc:/opt/app/app-manage/clock:ro --cap-add=SYS_ADMIN,SYS_RESOURCE container_image:tag

1.  The volume get successfully mounted.

            [root@abc /]# podman exec -it container_abc  /bin/bash
            [root@container_abc /]# df         ----> check the mounted volume.

       3.  [root@container_abc/]# ls -Z /opt/app/app-manage/clock
system_u:object_r:locale_t:s0 lost+found   ------------> volume mounted inside the container

       4. Stop the container to see  AVC denial:
              # podman stop container_abc
              # grep -i avc /var/log/audit/audit.log | ausearch -i | grep "unmount"
          node=localhost.localdomain type=AVC msg=audit(10/26/2023 18:38:35.774:1175336) : avc:  denied  { unmount } for  pid=278152 comm=umount scontext=system_u:system_r:container_init_t:s0:c246,c898 tcontext=system_u:object_r:locale_t:s0 tclass=filesystem permissive=0

Expected results

• AVC should not report {unmount} errors on podman stop.
• podman stop should unmoun the mounted volume.

Actual results

• AVC reports {unmount} errors on podman stop.
• podman stop does not unmount mounted volume.
