stable inclusion from stable-v6.6.33 commit 7880dbf4eafe22a6a41a42e774f1122c814ed02d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6SEY CVE: CVE-2024-38617

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

---------------------------

[ Upstream commit 998b18072ceb0613629c256b409f4d299829c7ec ]

The kv*() family of tests were accidentally freeing with vfree() instead of kvfree(). Use kvfree() instead.
