[PATCH] selftests/mm/cow: Modify the incorrect checking parameters

[Hao Ge]

From: Hao Ge <ge...@kylinos.cn>

In the run_with_memfd_hugetlb function, some error handle
have passed incorrect parameters.
It should be "smem", but it was mistakenly written as "mem".

Let's fix it.

Fixes: baa489fabd01 ("selftests/vm: rename selftests/vm to selftests/mm")
