memcg swap: use mem_cgroup_uncharge_swap fix
Although mem_cgroup_uncharge_swap has an empty placeholder for !CONFIG_CGROUP_MEM_RES_CTLR_SWAP the definition is placed in the CONFIG_SWAP ifdef block so we are missing the same definition for !CONFIG_SWAP which implies !CONFIG_CGROUP_MEM_RES_CTLR_SWAP. This has not been an issue before, because mem_cgroup_uncharge_swap was not called from !CONFIG_SWAP context. But Hugh Dickins has a cleanup patch to call __mem_cgroup_commit_charge_swapin which is defined also for !CONFIG_SWAP. Let's move both the empty definition and declaration outside of the CONFIG_SWAP block to avoid the following compilation error: mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin': mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap' if CONFIG_SWAP is disabled.
