Don't try to set devices fact when osd_auto_discovery was skipped (backport #7620)

[mergify[bot]]

Right now, under certain OS and Ansible versions, ie Rocky Linux and ansible-core 2.17, devices_check variable is getting defined even if task was skipped.

That results in set_fact to fail, as resulting variable has no results key in it.

Structure of such variable looks like that:

"devices_check": {
    "changed": false,
    "false_condition": "osd_auto_discovery | default(False) | bool",
    "skip_reason": "Conditional result was False",
    "skipped": true
}

Checking for task not being skipped solves such issues.
