We're checking for Restricted Admin Mode twice

[Sam Erde]

This appears to be a leftover from a previous PR that "moved" the Restricted Admin Mode check to the beginning of the script. I forgot to remove it here:

    if (!$Credential -and (Get-RestrictedAdminModeSetting)) {
        Write-Warning "Restricted Admin Mode appears to be in place, re-run with the '-Credential domain\user' option"
        break;
    }
