    Fix docker tag error when image has not been downloaded

    Sometimes, the python docker client pull command will finish without
    raising an error, but also not having downloaded the image, resulting
    in the next docker tag instruction to fail because the image does not
    exist, which will also halt the bootstrap process. This commit fixes
    this issue.

    Test Plan:
    PASS: Execute bootstrap until the end without issues aio-sx/dc-subcloud
    PASS: Execute prestage_images playbook without issues
