[PATCH 6/9] mm: Mark function as static in memcontrol.c

[Rashika Kheria <rashika.kheria@xxxxxxxxx>]

Mark function as static in memcontrol.c because it is not used outside
this file.

This also eliminates the following warning in memcontrol.c:
mm/memcontrol.c:3089:5: warning: no previous prototype for ‘memcg_update_cache_sizes’ [-Wmissing-prototypes]
