    Fix stale data cleanup on the logical volumes

    The stx-puppet tries to wipe the start and end of some logical
    volumes to prevent problems, but the command uses the wrong output
    file resulting in the creation of junk files. The command for scratch
    does not work since it's already mounted before the bootstrap. For this
    reason it was decided to unmount the filesystem before wiping the
    device's data.

    Depends-On: https://review.opendev.org/c/starlingx/ansible-playbooks/+/849047

    Test Plan:
    PASS: Perform bootstrap and restore-platform playbooks on centOS
    PASS: Perform bootstrap and restore-platform playbooks on Debian
