[PATCH] mm: hugetlb: correct CONFIG_CGROUP_HUGETLB macro name in comment

[Ethan Nelson-Moore]

A comment in <linux/hugetlb_cgroup.h> incorrectly refers to
CONFIG_MEM_RES_CTLR_HUGETLB, which has never existed in the kernel,
instead of CONFIG_CGROUP_HUGETLB. Correct it.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

Right, commit 2bc64a204697 ("mm/hugetlb: add new HugeTLB cgroup") introduced
that. Probably a leftover after reworks.
