Merge pull request #66694 from spiffxp/dd-status-none

Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. dd status=none does not exist on macOS **What this PR does / why we need it**: When running cluster/kubectl.sh on macOS 10.13.6, the use of the `status=none` operand leads to `dd: unknown operand status` being printed out as an error message. Redirecting to /dev/null does the same thing, supressing transfer status. ```release-note NONE ```
