mm: memcontrol: avoid unused function warning
commit 358c07fcc3b60ab08d77f1684de8bd81bcf49a1a upstream.
A bugfix in v4.8-rc2 introduced a harmless warning when
CONFIG_MEMCG_SWAP is disabled but CONFIG_MEMCG is enabled:
mm/memcontrol.c:4085:27: error: 'mem_cgroup_id_get_online' defined but not used [-Werror=unused-function]
static struct mem_cgroup *mem_cgroup_id_get_online(struct mem_cgroup *memcg)
This moves the function inside of the #ifdef block that hides the
calling function, to avoid the warning.
Fixes: 1f47b61fb407 ("mm: memcontrol: fix swap counter leak on swapout from offline cgroup")
