[PATCH v2 1/3] mm: vmscan: move set_task_reclaim_state() after cgroup_reclaim()

[Yosry Ahmed]

set_task_reclaim_state() is currently defined in mm/vmscan.c above
an #ifdef CONFIG_MEMCG block where cgroup_reclaim() is defined. We are
about to add some more helpers that operate on reclaim_state, and will
need to use cgroup_reclaim(). Move set_task_reclaim_state() after
the #ifdef CONFIG_MEMCG block containing the definition of
cgroup_reclaim() to keep helpers operating on reclaim_state together.
