mm/hugetlb_cgroup: fix -Wformat-truncation warning
A false-positive compile warnings with -Wformat-trucation was introduced
by commit 47179fe03588 ("mm/hugetlb_cgroup: prepare cftypes based on
template") on arch s390. Suppress it by replacing snprintf() with
scnprintf().
mm/hugetlb_cgroup.c: In function 'hugetlb_cgroup_file_init':
mm/hugetlb_cgroup.c:829:44: warning: '%s' directive output may be truncated writing up to 1623 bytes into a region of size between 32 and 63 [-Wformat-truncation=]
829 | snprintf(cft->name, MAX_CFTYPE_NAME, "%s.%s", buf, tmpl->name);
