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
