[PATCH 7/9] mm: Mark functions as static in page_cgroup.c

[Rashika Kheria <rashika.kheria@gmail.com>]

Mark functions as static in page_cgroup.c because they are not used
outside this file.

This eliminates the following warning in mm/page_cgroup.c:
mm/page_cgroup.c:177:6: warning: no previous prototype for a??__free_page_cgroupa?? [-Wmissing-prototypes]
mm/page_cgroup.c:190:15: warning: no previous prototype for a??online_page_cgroupa?? [-Wmissing-prototypes]
mm/page_cgroup.c:225:15: warning: no previous prototype for a??offline_page_cgroupa?? [-Wmissing-prototypes]
