memcontrol: move mm_cgroup to header file
Inline functions must preceed their use, so mm_cgroup() should be defined
in linux/memcontrol.h.
include/linux/memcontrol.h:48: warning: 'mm_cgroup' declared inline after
being called
include/linux/memcontrol.h:48: warning: previous declaration of
'mm_cgroup' was here
[akpm@linux-foundation.org: build fix]
