cpufreq: conservative: Simplify the condition of storing 'down_threshold' 

JIRA: https://issues.redhat.com/browse/RHEL-32446

commit 842c34a2668f68ebe15d0fc9dc19d33733bb428d
Author: Liao Chang <liaochang1@huawei.com>
Date: Fri, 06 Oct 2023 21:55:13 +0000

The governor currently checks if the input new down_threshold is less
than 100 before storing it, but the up_threshold field of dbs_data
structure is also limited to be less than 100, so this check is
unnecessary and remove it.
