[PATCH -next 2/2] kho: remove unnecessary WARN_ON(err) in kho_populate()

[ranxiaokai627 at 163.com]

From: Ran Xiaokai <ran.xiaokai at zte.com.cn>

The following pr_warn() provides detailed error and location
information, WARN_ON(err) adds no additional debugging value,
so remove the redundant WARN_ON() call.
