[PATCH v4 3/6] examples/l3fwd-power: fix uncore help and log info

[Huisong Li <lihuisong@huawei.com>]

The '-i' parameter is to set any uncore frequency rather than
min/max value. And the error logs are not clear enough, fix it
by the way.

Fixes: 10db2a5b8724 ("examples/l3fwd-power: add options for uncore frequency")
