Fix nvidia repo removal in patch_and_reboot

- in autoyast installation skip nvidia repo when it's unreachable, will be disabled later anyway
- nvidia repo wil be disabled only when present, thus exit 3 is not needed
- disable nvidia repo because following tests repos and clone will fail due to unreachable nvidia repo
