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

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 ‘__free_page_cgroup’ [-Wmissing-prototypes]
mm/page_cgroup.c:190:15: warning: no previous prototype for ‘online_page_cgroup’ [-Wmissing-prototypes]
mm/page_cgroup.c:225:15: warning: no previous prototype for ‘offline_page_cgroup’ [-Wmissing-prototypes]
